Highly Inert Capillary Columns with the Lowest Bleed Specifications -Guaranteed
- Accurate peak identification - achieving more reliable results
- Superior response for traces - better quantification
- Enhanced detector performance - increasing productivity and reducing costs
- Faster stabilization - longer instrument uptime, so increasing your productivity
The Varian FactorFour™ family of capillary columns provides a complete range of stationary phases suitable for industrial, toxicology, chemical and environmental applications. FactorFour highly inert ultra-low bleed columns offer a bleed specification up to four-fold lower than comparable competitive products.
Pursuit XRs Ultra 2.8 and Pursuit UPS 2.4 are designed to offer faster analysis with existing LC and LC/MS systems. They allow chromatographers to analyze samples faster while achieving higher resolution and reducing the cost per analysis without the need for capital investment. Both columns provide:
Method Development Flexibility - lower backpressures allow flows and mobile phases to be tailored to meet your applications needs
Maximum value. High performance separations achieved without the need for a new ultra high pressure system
Ion chromatography should be fun and should not get on your nerves. Metrohm does everything it can to ensure that your IC system will work reliably with minimum service, maintenance and costs. Metrosep separating columns stand for good quality, a long working life and excellent results.
Some of our new columns for ion chromatography:
Metrosep Dual 4 - 25
Separation of some standard anions in less than a minute, e.g. nitrate in just 45 seconds - faster than many FIA systems.
Metrosep A Supp 7 - 250
Separation column for the simultaneous determination of the standard anions, the oxo halides and dichloroacetic acid.
Metrosep A Supp 10 - 50
Allows very fast separations of the standard anions. Ideal for straightforward separation tasks and non-critical matrices.

Agilent J&W GC Columns are designed and manufactured to offer excellent and reproducible performance for the benign to the most difficult types of samples. With the lowest bleed levels, the best inertness for acids/bases/mixed functional compounds,and the tightest column-to-column reproducibility - Agilent GC columns are of higher quality and perform better than any other columns on the market.
Hypersil GOLD Columns
* Exceptional peak symmetry and resolution
* Based on next-generation ultra pure silica
* Outstanding pH stability
* Ideal first choice for new method development
Product Detail
Hypersil GOLD columns are a new LC and LC/MS column offering excellent peak shape. Based on highly pure silica, Hypersil GOLD columns provide symmetrical peaks, even when analyzing compounds that give notoriously poor peak shape on traditional C18 or L1 chemistries.
Rugged and robust manufacturing processes coupled with advanced column packing technologies produce highly efficient, reliable Hypersil GOLD columns for applications where resolution between compounds closely related in structure is paramount. Discrimination between such species is vital in drug analyses where active constituents and other trace components must be rigorously monitored. With L1 retention and selectivity, existing L1 methodologies are easily upgraded to Hypersil GOLD columns with minimal loss of time, but with an impressive gain in peak shape and sensitivity.
The 3µm and 5µm Hypersil GOLD columns are available in both unique and conventional formats, including standard analytical columns, KAPPA capillary columns, DASH high-throughput LC/MS columns, as well as several guard formats. Analytical columns and capillaries range in dimension from 75µm to 4.6mm ID and lengths from 20 to 250mm. For preparative work, Hypersil GOLD is also available in 8µm particle size and larger column dimensions, allowing ultimate flexibility in method development and transfer.
