Nicolet iN10 FT-IR Microscope - Liquid nitrogen expense calculator

Evaluate which detector offers the best convenience by entering values in the highlighted fields.. The room temperature detector provides sensitivity for samples as small as 50 mm, and applies best to non-mapping analysis. In scenarios where dozens of samples per day are run, the LN2 detector becomes cost effective.

The average LN2 hold time of a 25-liter dewar is about one month, depending upon usage. Samples of 100 mm or larger require less than a minute collection time with the room temperature detector. One year of utilization is calculated as 11 months.
