A piston and scraper assembly (26) for a high-pressure liquidchromatographycolumn (1) is provided with a snap lock between the piston (5) and the scraper (25).
Using reversed-phase chromatographic column and diode array detector, content of imidacloprid and pyridaben in their water soluble powder was measured with high effective liquidchromatography.
