Thermo Fisher, 042150, OmniPac™ PAX-100 HPLC Columns

Name: OmniPac™ PAX-100 HPLC Columns
Brand: Thermo Fisher
SKU: 042150

Length (Metric): 250 mm, Unit Size: Each, For optimizing separations of hydrophobic and halogenated anions, use the Thermo Scientific™ OmniPac™ PAX-100 Column. This polymer-based anion-exchange column is solvent compatible and stable over the entire pH range of 1-14. Solvents may be used to affect selectivity, solubilize otherwise insoluble samples, and to remove contaminants to prolong column lifetime. The OmniPac PAX-100 column is particularly well suited for the analysis of larger organic aci

FAQs

Question: What are the column dimensions?

Answer:This version is 4 mm internal diameter × 250 mm long.

Question: What stationary phase is used?

Answer:It uses a polymeric mixed-mode phase with alkanol quaternary amine anion-exchange functionality.

Question: What is the approximate ion-exchange capacity?

Answer:The column provides approximately 40 µeq ion-exchange capacity.

Application Note

OmniPac™ PAX-100 HPLC Column, 4 × 250 mm is used for high-resolution mixed-mode separation of hydrophobic and halogenated anions. The stationary phase consists of an 8.5 µm solvent-compatible microporous polymer substrate coated with latex particles carrying anion-exchange functionality. Its alkanol quaternary amine phase provides approximately 40 µeq ion-exchange capacity per column while also supporting reversed-phase interactions. The 250 mm analytical length gives more resolving power for complex mixtures than the shorter version. The column is stable from pH 0–14 and can be used with organic solvent to tune selectivity or dissolve difficult samples. It is especially suited to larger organic acids, alkylbenzene sulfonates, aromatic acids, barbiturates, polyphosphates, inositol phosphates, thiocyanate, thiosulfate, and iodate.
