Sensitivity Evaluation and Example Analysis of Microscopic Targets with Thermoelectrically Cooled MCT Detector

User Benefits

- A thermoelectrically cooled MCT detector can measure microscopic targets down to 25 µm in size without needing liquid nitrogen. - An MCT detector is compatible with transmission, reflection, and ATR method for analyzing a range of sample types. - For targets smaller than 25 µm, the standard T2SL detector can measure targets down to 10 µm in size with good sensitivity.

Introduction

Infrared spectroscopy is extremely useful for qualitative analysis of organic compounds and some inorganic compounds. Infrared microscopy can be used for spectroscopic analysis of microscopic targets that are otherwise difficult to analyze. The AIMsight Infrared Microscope and the infrared mode of the AIRsight Infrared/Raman Microscope are equipped as standard with the T2SL detector, which can analyze microscopic targets down to 10 µm in size if it is cooled with liquid nitrogen. However, the difficulties associated with procuring and handling liquid nitrogen mean there is increasing demand for infrared spectroscopic analysis of microscopic targets without using liquid nitrogen. The thermoelectrically cooled (TEC) MCT detector is a new optional detector in Shimadzu’s product lineup that can analyze microscopic targets down to 25 µm in size without liquid nitrogen. This Application News compares this new detector with existing detectors and presents two example analyses of microscopic targets using the new detector.
