A method of optical spectroscopy for analysing a sample using an optical spectrometer is provided. The method comprises obtaining a sample spectrum of the sample using the optical spectrometer and obtaining a blank spectrum using the optical spectrometer. The blank spectrum comprises structured background radiation which is correlated with the sample spectrum. A cross-correlation of the sample spectrum and the blank spectrum is determined. A mapped blank spectrum is generated by mapping the blank spectrum to the sample spectrum based on the cross-correlation, and the mapped blank spectrum is subtracted from the sample spectrum to generate a background corrected sample spectrum.

Optical spectrometer

A method of operating an instrument which comprises a first and second ion stores, comprising determining whether a target accumulation time for the second ion store is greater than a threshold accumulation time. When the target accumulation time is less than the threshold accumulation time, ions are accumulated within the second ion store using an accumulation time that is based on the target accumulation time. When the target accumulation time is greater than the threshold accumulation time, ions are accumulated within the first ion store using a first accumulation time that is based on a difference between the target accumulation time and the threshold accumulation time, the ions accumulated in the first ion store are passed to the second ion store, and further ions are accumulated within the second ion store using a second accumulation time that is based on the threshold accumulation time.

Ion accumulation control for analytical instrument

A method of processing two dimensional optical spectra, such as echelle spectra, is disclosed. The optical spectra comprise sections having a relatively high intensity separated by borders having a relatively low intensity. The optical spectra have been digitized () by a detector. The method comprises denoising () an optical spectrum, searching () for at least one series of neighboring local extrema of the optical spectrum, fitting () a line through each series of neighboring local extrema, each line representing a section, identifying () any peaks and their respective locations, and storing () the lines and the locations of any peaks.
