When analyzing chloroform with raman spectroscopy，is there a plausible way to reduce the noise other than repeating the process?

There are a few ways that can decrease the noise in spectra.

TEC: If have a spectrometer that uses a thermoelectric cooler, for example, a NIRQuest or QE spectrometer, please make certain that the TEC and fan are empowered and it is set to the suggested setpoint.

Unprocessed mode intensity: The best estimations are made when the natural mode force in tallies is in the vicinity of 80 and 90% of the quantity of numbers where the locator winds up noticeably immersed. If don't mind check the area in which are seeing the commotion to check whether the numbers are in the vicinity of 80 and 90% of where the finder ends up plainly soaked . In the event that the numbers are much lower than this, please increment the combination time to get the flag near or inside this level. If don't mind take note of that expanding reconciliation time builds the quantity of tallies through the whole range and relying upon the grinding in r spectrometer and the light being measured, there might be some locale that ends up noticeably immersed when the coordination time is expanded. Any pixels that are soaked won't yield great information. The information is scaled so that a spectrometer's indicator winds up plainly soaked at 2 to the energy of the quantity of bits of the A/D converter short

Scans to average The Scans to normal default is 1, which implies that the spectrometer does one sweep and that is r obtaining. The more sweeps to normal utilize, the more prominent the flag to clamor proportion. If it's not too much trouble take note of that r aggregate obtaining time will be the quantity of sweeps to normal increased by the incorporation time.

Boxcars: Using few train units will build the flag to clamor proportion; be that as it may, it will likewise straighten the pinnacles. It regards use between 1-5 freight cars.

Integration time:As increment reconciliation time, the rate of commotion in the flag will increment. We characterize the greatest incorporation time of our spectrometers as that mix time whereby the commotion includes half of the aggregate flag. On the off chance that can utilize a bigger distance across fiber, and so forth to have the capacity to utilize a shorter coordination time.

Detector Temperature: Noise increments with increments to locator temperature. In the event that r spectrometer does not have a TEC, attempt to work in a cooler temperature condition.
