FGC-1610 4-dichlorophenoxyacetic acid determination of the special gas chromatograph

scope
0 ~ 2,4-dichlorophenoxyacetic acid (hereinafter referred to as 2,4D) pure white crystals at room temperature, the melting point of 14141 ℃, widely should Preservation citrus. The study shows that the substance can induce bladder cancer, in Western countries limited application, and strengthened the fruit of 2,4-D monitor citrus 2,4D liquid chromatography (HPLC) assay commonly used, this method using ether complex salt. - methanol as the acidic catalyst so that 2,4-dichlorophenoxyacetic acid into 2,4-dichloro-phenoxy acetate, followed by gas chromatography .

Features
Large-screen LCD English display. Easy to learn.
※ with self-diagnosis, over-temperature shutdown protection, file storage, recall, fifth-order temperature-programmed functions, with single-column automatic compensation function; to ensure the stability of the baseline temperature programmed analysis.
※ instrument has dual packed column inlet capillary column three, three gas independent way.
※ with six independent temperature control area, after intelligent door systems, cooling is very fast; each of the gasification chamber, detector and amplifier are modular design, installation is very easy to replace.
※ complete with a separate capillary analysis system, an independent capillary split sampler (includes a diaphragm cleaning, split and tail blowing conditioning). Optional capillary split / splitless injector.
※ instrument equipped with a flame ionization detector, thermal conductivity detector, a flame photometric detector, electron capture detector, NPD five kinds of detectors, three detectors can be installed, the user can according to their own self-analysis requires optional , also increase the six-way injection valve, reformer devices; and to achieve detector series and parallel work.
