To turn on the Raman spectrometer press the button on the machine (Figure 1). The sample is placed on the stage inside the sample compartment (Figure 2), and to move the stage in X, Y, and Z directions, use the microscope stage controls (Figure 3).

## Procedure

### Setup/ initialisation

1. Before starting any measurements, please book the Raman machine beforehand through Skedda Website by first registering your email to the Skedda system. Link: <https://management.apcresearch.org/resources/lab/raman>
2. Before turning on the instrument, please make sure that the AC inside the room is turned on. Check the temperature and relative humidity of the room and make sure the temperature of the room is below the upper limit temperature of 27°C and stays that way throughout the analysis process. (If the temperature of the room reaches 28°C, stop all measurements and remove your sample from the sample compartment and wait until the temperature of the room to stabilize to begin your analysis).
3. Write down the sample details in the logbook, and ensure the water level in the water container of the humidifier is not overloaded or exceeding the marked limit. If the water level exceeds or approaching the marked limit, then please empty the water container before performing an experiment.
4. Before beginning any spectra acquisition, please first measure the SiO2 and HOPG standard reference.

### Powering up the instrument

<figure><img src="/files/LMtQKKdGnDs8TM4A5peW" alt=""><figcaption><p>Figure 4. The blue LED is turned on, indicating that the power source of the stage motor is successfully switched on.</p></figcaption></figure>

1. Turn on the power source for the stage motor by pressing the green button, the cable light will turn blue if the power source for the motor has been turned on successfully (see Figure 4). Wait for 30 minutes.
2. Power up the instrument, hold down the power button for 3 seconds and make sure the power indicator turned blue. Wait for 30 minutes.
3. Turn on the computer.
4. Turn on the laser by turning the laser key on the left side of the instrument to an upright position (Figure 5) and make sure that the laser power indicator is on. Wait for 30 minutes.

<figure><img src="/files/4yBJjuW5g0ogkapCzKdT" alt=""><figcaption><p>Figure 5. Laser key on unlocked position.</p></figcaption></figure>

5. Turn on the illuminator (Figure 6).

<figure><img src="/files/nQAsjzdJcNpNdzqdW2X9" alt=""><figcaption><p>Figure 6. Olympus TH4-200 illuminator.</p></figcaption></figure>

6. Make sure that there are no samples inside the compartment prior to booting up the software to avoid an error during the stage calibration.
7. Open the OMNICxi application and wait until the boot up process is finished.
8. Wait for 10-15 minutes for the laser to warm up.
9. The instrument is ready to use.

### Raman spectra acquisition of samples

1. During the experiment you will spend most of your time in the acquisition screen.
2. For this example, a carbon-based material such as Highly Ordered Pyrolytic Graphite (HOPG) or a silicon wafer can be used as a calibrated standard.
3. To begin spectra analysis, prepare the sample by introducing the sample to an appropriate supporting substrate (silicon wafer or microscope slide) with a double tape or carbon tape to avoid from spilling the sample all over the stage, ideally such substrate should have contrasting color as the basic criterion when probed by Raman instrument.
4. Place your sample inside the stage and make sure that the sample is directly under objective lens using the stage controller (X and Y axis of the stage, see Figure 3). First use the 10x magnification.
5. When the sample is directly under the objective lenses, adjust the focus by turning on the knob on the right side of the controller (Z-axis control of the stage, see Figure 3) whilst paying close attention to the video panel. To speed up the process hold down rectangle button near the knob, if you observe that sample is in close proximity to the objective lens, then gently turn the knob to avoid bumping the sample into the objective lens until reaching the appropriate focus.
6. After adjusting the focus on the video panel, choose a region of interest (ROI) of sample surface for the spectral analysis using the stage controller.

<figure><img src="/files/ARoZEwxCDaCUuAdck6wl" alt=""><figcaption><p>Figure 7. Choose Region of interest using the stage controller.</p></figcaption></figure>

7. After choosing an appropriate surface, choose the desired parameters to set up for your sample. **Avoid using the laser at high power from the start to avoid burning your sample.** For example, start the parameter at 1 mW laser power, 325 Hz exposure time and 10 number of scans. If the spectrum displays a lot of noise, gradually increase the parameter, starting from the number of scans to increase the signal to noise ratio and then the laser power and exposure time.

<figure><img src="/files/UNdPtUgU90szVr2SqyG4" alt=""><figcaption><p>Figure 8. Set up the desired parameter, you can also set it during live spectrum tab.</p></figcaption></figure>

8. After setting up the desired parameter, click on the “live spectrum” tab, wait until the live spectra panel shows a live spectrum of the sample.

<figure><img src="/files/jRpQiMdzv4hgTPIMWbE7" alt=""><figcaption><p>Figure 9. click live spectrum tab.</p></figcaption></figure>

9. You can change the parameter if the signal-to-noise ratio is still low by increasing the number of scans and increasing or decreasing the laser power and exposure time, if needed, just be careful not to burn your sample.
10. To save your spectra click the “save spectrum” button and save the .spa spectrum in the appropriate folder path. (Alternatively, you can right-click on the spectra when you’re on the video mode and click “export” into .txt file).

<figure><img src="/files/T409Se92gYN9yxuNJGc3" alt=""><figcaption><p>Figure 10. Ways to save spectra.</p></figcaption></figure>

11. The HOPG sample should have two distinctive Raman bands at around 1580 and 2721 cm-1, corresponding to G and D band. Whereas, a single peak centered at 519 cm-1 is observed for a SiO2 wafer.
12. Take out the sample by first clicking the “Video” tab, after that open the sample compartment and lower the stage using the Z-axis controller. After the sample is far enough from the objective lenses, gently move the stage away using the X, Y axis controller and then take out the sample.

<figure><img src="/files/ZH7L4RYt6GCBIGPdskC3" alt=""><figcaption><p>Figure 11. Results of SiO2 wafer and HOPG standard reference.</p></figcaption></figure>

### Raman imaging mode acquisition

If a PV wavelength accuracy test fails (peak location is outside the specified limits), use OMNIC software to open the spectral (.SPA) file from the most recent PV test. The most recent PV test files (polystyrene spectrum and image map) are located here:

`Thermo/OMNICxi/Spectra/PV`

If the spectrum contains excessive instrument noise (spikes), the polystyrene sample may have been out of focus. Rerun the PV test making sure the focus is correct.

If a wavelength accuracy test fails again, align and calibrate the installed laser set and then rerun the PV test. If a wavelength accuracy test fails again, contact us.

If the PV image resolution test failed (measured line spacing is outside the specified limits\_, open the image map from the most recent PV test (see location above). The map should contain vertical lines as in this example:

![Figure 23 Mapping results with vertical lines](/files/xcXtbFAfizsqDWy7DPzr)

If there are no vertical lines in the collected map, check the following and then rerun the PV test:

Make sure the silicon test sample is right side up (the wording on the sample should be right side up when you are looking at the sample through the microscope)

Make sure the 50x objective is fully rotated into the front objectve position

Make sure the correct video calibration for your 50x objective is selected in the OMNICxi Acquisiton window so the scles are synchronized

Make sure the sample is in sharp focus

Make sure the crosshair in the microscope eyepiece is centered on the period in the “0.25” feature on the test sample

If the image resolution test fails again, contact us.

<summary>Sample Bands Are Too Large or CCD Overflowed</summary>

The Raman signal is too large, which saturates the CCD. You can decrease the signal by doing one or more of the following:

\-        Decrease the setting of exposure time in the software

\-        Decrease the aperure size by setting in the software

\-        Select a pinhole aperture instead of a slit aperture

\-        Decrease the setting of laser power in the software

\-        Make sure all doors of the system are tightly closed

If this problem persists, contact our sales or service representative in your area

</details>

<details>

<summary>No Raman Signal Appears in the Live Display or Spectrum Has No Sample Bands</summary>

</details>

<details>

<summary>The Spectrum Has a Sloping Background or a Severe Positive Offset</summary>

The sample may be heating. To account for this condition try one or more of the following:

* Use a different laser (shorter wavelengths heat samples less)
* If the sample looks burned, replace it or move it so the laser will strike a fresh area
* Reduce the laser power and collect the sample again

Watch the live display to see if the sample is still heating (Reducing the laser power reduces the Raman signal generated at the sample and terefore the quality of the data. To compensate, try increasing the number of scans or exposure time)

* Reduce the wcposure time and collect the sample again
* Turn on baseline correction in the settings panel

If this problem persists, contact our sales or service representative in your area

</details>

<details>

<summary>The Spectrum Baseline is Severely Tilted, Curved or Saturating</summary>

The sample is fluorescing during data collection. To correct this problem, try one or more of the following:

* Turn on baseline correction in the settings panel
* Use a longer wavelenth laser
* Go to live spectrum mode and expose the sample to the laser beam for a period of time before beginning the collection of the sample spectrum. This is known as “Photobleaching”. Photobleaching time can be automatically added t an image collection on the advanced tab of the acquistion settings
* Make sure the slide, coverslip or other sample properties are not responsible for the fluorescence

If this problem persists, contact our sales or service representative in your area
