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 ...
Sterlitech Syringe Filters play important roles in the purification processes inside laboratories and out in remote operations—applying to sample preparation for HPLC, pharmaceutical dissolution testing, and environmental monitoring, to name a few. ...
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 ...
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 ...
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'. ...
