MCR AR
MCR-AR is a commerically available extension, that features a peak detection and deconvolution based on Multivariate Curve Resolution with Alternating Regression.
MCR-AR uses as input data segments of 50 to 500 scans. Several methods to automatically determine these analysis segments are available.
The data for each analysis segment is then preprocessed with background removal, linear baseline correction and removal of mass channels that contain only noise.
