Restek Force Biphenyl, 1.8 µm, 100 x 2.1 mm LC column, 9629212

Description:
Force Performance LC columns are the result of more than 20 years’ experience in liquid chromatography and are characterised by their durability and reproducibility, even under the stresses of UHPLC. Their first-class quality is backed by our 100 per cent satisfaction guarantee. And perhaps most importantly: Force columns are fully scalable between 3 or 5 µm HPLC and 1.8 µm UHPLC, allowing you to easily transfer and optimise methods without extensive calculations. Use Force LC columns for all your HPLC and UHPLC instrument platforms.

The innovative biphenyl phase is Restek’s most popular stationary phase, as it is particularly well suited to the separation of compounds that are difficult to dissolve or that elute early on C18 columns and other phenyl phases. Biphenyl columns are therefore extremely useful for bioanalytical testing applications such as drug and metabolite analyses, particularly those requiring a mass spectrometer (MS). Increasing the retention of early-eluting compounds can limit ionisation suppression, and the enhanced selectivity helps to avoid the need for complex mobile phases that are not well suited to MS detection.

Properties
:- Increased retention for dipolar, unsaturated or conjugated solutes
.- Improved selectivity when used with a methanolic mobile phase
.- Ideal for increasing sensitivity and selectivity in LC-MS analyses.

Switch to a biphenyl column
:- If you notice limited selectivity
on a C18 column.- If you need to increase the retention of hydrophilic aromatics.

Features and benefits
: - Ideal for bioanalytical testing applications such as drug and metabolite analyses
.- Increased selectivity and retention for compounds that are difficult to resolve on C18 columns and other phenyl phases, or which elute early
.- Limits ionisation suppression and enables simple, MS-friendly mobile phases.
- Restek’s most popular stationary LC phase.
