Photochemical derivative device

1Photochemical derivative deviceOverview:

(1) Due to the strong fluorescence of B1 and G1, they undergo quenching of fluorescence upon contact with water, and their fluorescence basically disappears, making them difficult to detect by liquid chromatography. So we can use derivative methods to enhance the fluorescence of B1 and G1.
(2) This photochemical derivatizer does not require any chemical reagents and is directly connected between the chromatographic column and the fluorescence detector, with simple operation, accurate detection results, and high sensitivity.

2、 After sales service policy: From the date of sale, if there is any quality problem with this product, it will be returned within one month and replaced within one year!
