Agilent’s linearized mercury cadmium telluride (MCT) detector technology delivers substantial advantages for quantitative measurements. It extends the linear range of the detector versus energy flux relationship by about a factor of ten above the range that can be obtained with a standard MCT detector, while still maintaining high photometric accuracy. As a result, a wider concentration range can be achieved when performing quantitative measurements, so you can avoid time-consuming dilutions, providing greater productivity and lower running costs for your laboratory.
Agilent's linearized mercury cadmium telluride (MCT) detector technology extends the linear range of the detector versus energy flux relationship by about a factor of ten compared to standard MCT detectors. This extension allows for a wider concentration range during quantitative measurements, reducing the need for time-consuming dilutions and lowering running costs for laboratories.
Standard MCT detectors exhibit a non-linear response at high incident energy, leading to errors in photometric measurements. Agilent addresses this by using a ten-stage non-linear pre-amplifier network that is individually calibrated to each detector. This method corrects the non-linear response without increasing the noise level, maintaining high photometric accuracy and better sensitivity than non-linearized detectors.
The amount of detector saturation should generally be less than 5% to maintain photometric accuracy.
The compensation allows for operation up to 80 KHz in collecting IR spectra.
