Specifications (Low UV Type)

The ion-pair chromatography is a method for separating and analyzing a sample containing electrolytes by adding excess counter-ions to the mobile phase to make the sample into undissociated complex molecules so that the sample can be analyzed by reversed-phase chromatography. Low UV Type ion-pair reagents have extremely reduced UV absorption in the short wavelength range. They are suitable for analysis using short-wavelength UV in which the background is high and a large amount of noise is generated if a conventional reagent is used. Since they come in a solution form, they can be easily dissolved in any mobile phase. For components having acid functionality, use quaternary alkylammonium salt, and, for components having basic functionality, use alkylsulfonate salt.
