Reducing Acetonitrile Consumption
The acetonitrile shortage is generating concern for chromatographers around the world. Here we explore strategies for reducing consumption.

THE SWAP IT GC Interface
The Thermo Scientific SWAP-IT GC Interface enable fast column changes without the need to vent a mass spectrometer. The interface is compatible with Thermo Scientific and Agilent GC-MS instruments.

Introducing the SRS Pro for Recycling HPLC Solvents
In the present economic climate, the conservation of solvent used for liquid chromatography mobile phase has become an important consideration. The Thermo Scientific SRS Pro provides a means of recycling precious solvents.

Comparing GC Septa
We compare the bleed levels, longevity and sealing capabilities for a number of leading brands of septa.

Introducing the UHPLC Filter
The UHPLC filter provides protection of your UHPLC column without compromising its performance.

GLD Pro Gas Leak detector
Leaks in a GC system produce baseline instability, bleed, poor sensitivity and poor peak, as well as other problems. The GLD Pro is a useful tool for checking your system for leaks.

Hypersil GOLD Javelin HTS
Analysis time is a major consideration with new methods. The use of short, small particle columns can still provide good separations with short run times.

Vials and Seals: The right choice for HPLC
The range of vials and seals available for HPLC is broad. We discuss how to choose the right products for your application.

Using Solvent Recycling to Save Solvent in HILIC Separations
The SRS Pro solvent recycler is evaluated and used to achieve mobile phase cost savings when carrying out HILIC separations.

Understanding the Move to Fast LC
Small sub-2um particle packed HPLC columns provide many opportunities for reducing time and cost. This clip explains these column advances and how to take advantage of them.

A Comparison of Polymeric, Porous-Graphitic-Carbon and Silica for Solid Phase Extraction
Polar modified polystyrene-divinylbenzene and porous graphitic carbon (PGC) demonstrate important advantages over more conventional silica based sorbents for solid phase extraction. Here we investigate the characteristics of these materials.

The Effect of Column Position in the GC Instrument
We take a look at the the incorrect positioning of a GC column in the injector or detector, and the impact the quality of the chromatographic data generated.

An Introduction to Solid Phase Extraction
Solid Phase Extractions (SPE) is a technique for cleaning complex samples for subsequent analysis.

SPE Methodology
Solid Phase Extraction (SPE) is a simple 5 step process that can be tailored to many different sample types.

SPE Phase Chemistries
Solid Phase Extraction (SPE) tubes and cartridges are available packed with a range of silica and polymeric modifications.

SPE Method Development
Solid Phase Extraction (SPE) method development includes selecting the right packing type, size and solvent systems.

SPE Phase Selection
Selecting the correct packing material for your sample clean up requires you to understand and properly define your requirements, including knowing something about your sample.

SPE Troubleshooting
Introducing the concept of troubleshooting solid phase extraction (SPE) separations.

The Importance of Conditioning Your GC Column Before Use
It is important to condition your GC column before using it in order to minimise bleed, improve sensitivity and prolong its useful life.
