Differential Scanning Calorimetry (DSC)
Differential scanning calorimetry (DSC) measures Specific Heat Capacity, Heat of Transition, and the Temperature of Phase Changes and Melting Points. DSC measures the rate of heat flow, and compares differences between the heat flow rate of the test sample and known reference materials. As a sample undergoes a transition (melting, crystallization, etc.), heat is absorbed or emitted. This change in heat flow is then measured by the system and can be analyzed. The difference determines variations in material composition, crystallinity and oxidation.

Mid-Range Gas Filter Correlation CO Analyzer
Model N300M
Teledyne Advanced Pollution Instrumentation
The Model N300M is a microprocessor-controlled analyzer used to determine the concentration of carbon monoxide (CO) in a sample gas. The analysis method is based on the Beer-Lambert law.The N300M uses Gas Filter Correlation (GFC) to overcome the interfering effects of various other gases (such as water vapor) that also absorb IR. The analyzer passes the IR beam through a spinning wheel made up of two separate chambers: one containing a high concentration of CO known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO in the sample chamber is computed by taking the ratio of the instantaneous measure and reference values and then compensating the ratio for sample temperature and pressure.
