Fully automated microwave digesters, as a sample pre-treatment device, are becoming an important tool in laboratories due to their speed, efficiency, and precision. ...
The results showed that the addition of pectinase has almost no effect on the sugar and acid content of grape juice, but it can reduce the viscosity of the juice and facilitate the dissolution of pigments. The samples with pectinase fermented more vigorously and faster than those without pectinase, which can reduce the amount of volatile acid produced, increase ...
This application note will focus on a rapid test method for determining mercury directly in soils and river sediments using the principles of thermal decomposition, amalgamation and detection by atomic absorption described in EPA Method 7473 and ASTM Method 6722-01. Because there is no sample dissolution required, this novel approach can determine the total ...
This application note will focus on a rapid test method for determining mercury directly in food materials and agricultural crops using the principles of thermal decomposition, amalgamation and detection by atomic absorption described in EPA Method 7473 and ASTM Method 6722-01. Because there is no sample dissolution required, this novel approach can determine the ...
Overall, laboratory error should be small and well controlled; otherwise, lapses in quality can easily lead to substantial error. Sample Dissolution An acid digestion or extraction procedure must achieve reproduceable results for the contaminant of interest in any of its likely physical or chemical forms. The procedure should allow ample time for the ...
Core sampling improves the accuracy of the sample definition. Compositing increases the sample support, improving the sample's ability to represent a particular sample area, or 'sampling unit'. ...
