Anion chromatography columnNj-to- 9 AInstrument Introduction:

The filler is an anion exchange resin with quaternary amine functional groups. Using carbonate as a eluent, the conductivity background is extremely low,High sensitivity,One injection can be completedF-，ClO2-，Cl-，NO2-，Br-，NO3-，PO43-andSO42-Separation of eight anions.

Technical Specifications:

　　NJ–SA–9AAnion chromatography columnIt is an anion exchange resin with quaternary amine functional groups as fillers. Extremely low conductivity background,High sensitivity,One injection can be completedF-，ClO2-，Cl-，NO2-，Br-，NO3-，PO43-andSO42-Separation of eight anions.

Its advantages are as follows:

　　1. Low column pressure,long service life

　　2. Easy to operate, no need for gradient rinsing, and the rinsing solution is affordable

　　3. Good stability

　　4. Baseline separation of water negative peak and fluoride ions,Does not affect the quantitative analysis of fluoride ions

　　5. High crosslinking resin based core, compatible with organic solvents

　　6. Organic solvents can effectively flush the column

　　NJ–SA–4AAnion chromatography columnThe nucleus is ethyl vinyl benzene/Macroporous copolymer of divinylbenzene with crosslinking degree of55%Its various performance indicators have reached the level of similar foreign products. Currently, it has been equipped by ion chromatography manufacturers nationwide,Effectively improved the overall performance and market competitiveness of domestic ion chromatography.

Storage solvent

Do not store the chromatography column for a long time in a water filled environment, store it in a water filled environment3The sky above will be conducive to the growth of microorganisms and damage the pillars. Save the column with eluent and use carbon chromatography columnsuansodium/carbonsuanSodium hydrogen leaching solution. Store in the refrigerator for no less than4℃保存。
