无孔硅胶柱（比安捷伦柱、沃特斯柱分离更快）

Micra NPS® (non-porous silica) HPLC columns - See Technical Note: Short Run Times - Reduced MP Solvent Usage High Sensitivity & Resolution Greatly Improved Mass Transfer Kinetics Increased pH stability ODS-I MICRA NPS ODS-I - polymeric C-18 bonded phase on 1.5µ NPS. See Application Note See Application Note See Application Note See Application Note Small drug molecules to biomolecules can be rapidly analyzed with ODS-I columns. With the addition of modifiers such as TEA, excellent peak shapes for many basic compounds such as TCA's can be obtained. This is an excellent column for high throughput and QC lab applications as well as LC/MS separations. The absence of porosity in NPS columns makes them suitable for the direct injection of plasma for metabolite analysis. ODS-IIIE MICRA NPS ODS-IIIE - Endcapped C-18 bonded phase on 1.5µ NPS See Application Note This is an excellent column for high throughput and QC lab applications, as well as LC/MS separations. The endcapping on ODS-IIIE columns delivers excellent resolution and analysis speed with low peak tailing for basic drug compounds. NPS-TAS MICRA NPS TAS - a C-30 coating on 1.5µ NPS for use in specialty separations See application Note See Application Note NPS-Sil MICRA NPS-Sil - non-bonded 1.5µ NPS. These columns are highly efficient for all normal phase applications and work particularly well with very polar compounds. The surface silanols are only slightly acidic. NPS-PAH MICRA NPS-PAH - polymeric bonded C18 phase on 1.5µ NPS. See Application Note This PAH column offer high sensitivity, superior reproducibility, and the baseline separation of 16 PAH's in less than 10 minutes.
