Overview / Applications
Outline | The solid-phase extraction method, as pretreatment of samples for HPLC and GC analyses, has advantages including reduction of labor and decrease of solvent usage, and now is frequently used instead of conventional methods with extraction solvent. It is also often used in the official methods for environmental and food analyses. There are two types of solid-phase extraction cartridges as follows: a syringe type with one end open (tentatively called "open type"), and a cartridge type with a filler enclosed in it that can be connected to a syringe (tentatively called "closed type"). This is a closed type product with DNPH enclosed in it. Presep-C DNPH is a special collection tube for atmospheric carbonyl compounds (designated by the Offensive Odor Control Law, the Air Pollution Control Law, and U.S. EPA) to be used for its collection as well as for derivatization by 2,4-dinitrophenylhydrazone (DNPH). The product is characterized by its blank components from the cartridge where formaldehyde, acetaldehyde and acetone have been especially reduced. Through the analysis of these, it can assure high measurement accuracy. For the exterior, a polyethylene cartridge of lure fitting type is applied, which makes connection or handling during air collection and solvent extraction easier. |
