Microextraction Techniques in Illicit Drug Testing: Present and Future [PDF]
Bioanalysis, 2016 Sample preparation is of utmost importance in both qualitative and quantitative analysis of illicit drugs because complex matrices, such as biological specimens, are involved in the assay. In forensic toxicology, the analysis is typically performed on biological fluids such as urine, serum and plasma.

Soaking Water Management Strategies for Enhanced Quality of Parboiled Rice
Cereal Chemistry, EarlyView.ABSTRACT Background and Objectives Parboiling is a hydrothermal process that alters rice physicochemical and nutritional properties. The soaking step is crucial, influencing off‐flavor formation, mineral retention, and effluent quality. This study evaluated five soaking water (SW) management strategies combining different frequencies and volumes of SW ...
