RP-HPLC chromatographic column

Usage and application suggestions

Eclipse Plus

The chromatographic column developed by the method; Acidic, alkaline, and neutral compounds can be reliably separated at pH 2-9 and have a long lifespan; Excellent peak shape for the separation of alkaline compounds; 1.8, 3.5, and 5 µ m chromatography columns have high separation and column efficiency; Through rigorous QA/QC testing, ensuring long-term reproducibility

Eclipse XDB

There are four options to choose from, allowing for flexible method development; High performance within a wide pH range (PH2-9); Has excellent peak shapes for acidic, alkaline, and neutral compounds; Ultra tight bonding and double sealed ends extend the lifespan; Use 1.8 and 3.5 µ m chromatography columns for rapid, ultra high speed, and high resolution separation; There are capillary columns to prepare columns to choose from

StableBond(SB)

Alkaline, acidic, and neutral compounds; Especially stable at low pH values; Using high temperature (up to 90 ℃ for C18 and up to 80 ℃ for C8, C3, phenyl, cyano, and Aq) and low pH as selective means to increase selectivity; There are multiple bonding phases available for different selectivity options (C18, C8, C3, cyano, phenyl, etc.) Aq）; LC/MS mobile phase containing formic acid, acetic acid, or trifluoroacetic acid (TFA) can be used; Proteins and peptides can be separated using a mobile phase containing trifluoroacetic acid (TFA); Rapid separation using 1.8 and 3.5 µ m chromatography columns

ZORBAX Rx

The universal column for separating alkaline, acidic, and neutral compounds at low pH values has different selectivity compared to the SB column;

Rx-C8 is the same as SB-C8S

Bonus-RP

Separate alkaline compounds using a mobile phase with high water content; A universal column for separating alkaline, acidic, and neutral compounds at medium or low pH; Especially stable at low pH; Separate peptides with different selectivity; Using a 3.5 µ m chromatographic column for rapid separation

Extend-C18

Separate free forms of alkaline compounds above their pKa; Separate alkaline, acidic, and neutral compounds under high pH conditions; The maximum pH can reach 11.5; Using amine hydroxide as the mobile phase for LC/MS separation of small molecule compounds or peptides; Separate at high, medium, and low pH levels to alter selectivity; Using a 3.5 µ m chromatographic column for rapid separation

Usage and application suggestions

ZORBAX

The universal separation of alkaline, acidic, and neutral compounds at low pH is different from the selectivity of SB chromatography columns; Under relatively neutral pH conditions, the number of active silanol groups separated in 'mixed mode' exceeds that of SB column

ZORBAX ODS Classic (unsealed)

A universal column for separating alkaline, acidic, and neutral compounds at medium to low pH values, with different selectivity compared to SB or XDB chromatography columns
