Aurora`s TRANSFORM series of microwave digestion systems, offers high-pressure and temperature systems in order to increase reaction rates and decrease digestion times for sample preparation for trace metal analysis in soil.
Direct atomic absorption mercury determination (without any pre-treatment procedures) in food is complicated by its organics matrix. That is the reason why almost all AAS methods of mercury determination in foodstuff include sample digestion by acids.
This analytical procedure is intended for measuring the content of the elements (cadmium, lead, arsenic, tin, chromium and mercury) in the samples of food products by atomic absorption spectrometry with electrothermal atomization using an “MGA-915M” Graphite Furnace AA Spectrometer.
The method is based on measuring resonance radiation absorption that occurs when the radiation passes through a layer of atomic vapor in the electrically heated graphite furnace of the “MGA-915M” AA spectrometer....
A conventional standard method of total mercury determination in water using atomic absorption spectrometry (AAS) involves preliminary sample digestion that takes from 30 minutes to 8 hours depending on the digestion conditions.
The use of a mercury analyzer RA-915M/RA-915+ with Zeeman background correction in combination with PYRO-915+ pyrolysis attachment provides direct determination of mercury in process and waste waters contaminated with mercury without digestion or any other sample preparation stages.
Testing phosphonates in hard water can be difficult due to interference from high levels of calcium. Here we present a phosphonate test method for hard water samples. The method is based on a chemical masking of the calcium.
The WAT hard water phosphonate test uses C30 Spectrophotometer to measure the chromogen PMB and digital thermoreactor to digest the phosphonate compound.
The thermoreactor capacity of 16 simultaneous vials provides for running critical data quality assurance samples.
Peptide mapping is an essential step in the structural verification of recombinant proteins and biotherapeutic molecules. In this technique, proteins are digested into peptides, fractionated by traditional liquid chromatography (LC) methods and then analyzed by Mass Spectrometry (MS). Although this approach can be effective for many peptides, it is slow (often 30 minutes or more per sample), requires complex sample preparation and is incompatible with some sample types such as “sticky” peptides. The...
