The Determination of Total Mercury in Soils and River Sediments Using Thermal Decomposition and Amalgamation Coupled with Atomic Absorption
05 Nov 2009: This application note focuses on a rapid test method for determining mercury in soils and river sediments using the principles of thermal decomposition, amalgamation and detection by atomic absorption. This novel approach can determine the total mercury content of a soil or sediment sample in less than five minutes, which is significantly faster than the traditional wet chemical reduction method.

Thermodynamic Investigation of an Enzyme-Inhibitor Pair
22 May 2009: Understanding the thermodynamics of a system gives valuable insight into the mechanism and forces leading to an interaction. Reichert’s SR7000DC system provides the opportunity to acquire thermodynamic data for molecular interactions of interest owing to its precise temperature control from 10 oC below ambient to 90 oC. This application note utilizes the SR7000DC system to characterize the thermodynamics of a small molecule inhibitorenzyme pair.

The new STA 449 F1 Jupiter®: Unlimited Flexibility in Simultaneous Thermal Analysis
22 Jul 2008: Simultaneous Thermal Analysis (STA) is an established method for material characterization which measures mass changes and caloric effects on one sample at the same time using a controlled temperature program. This application note shows measurements on a Fe(OH)SO4 sample that were done using an STA 449 coupled to a mass spectrometer. This is a possible base material for the manufacture of iron oxide particles, which can be used as magnetic storage media or in ferrofluids.
