Flowmeters that can measure flammable gases are becoming mandatory, due to the increased use of hydrogen in chromatography.With its Ex rating, the Restek ProFLOW 6000 Flowmeter is designed specifically with explosive and flammable gases in mind.

The new Restek ProFLOW 6000 is the only flowmeter you need for any type of chromatography gas measurement because of its wide range of capabilities. The ProFLOW 6000 is an electronic device capable of measuring bidirectional volumetric flow for most gases.

Real-time measurements can be made for various types of flow paths, including continually changing gas types. This portable unit is designed for easy hand-held use, and the stand adds bench-top convenience.

State-of-the-art features include:

• • Measures volumetric flow for all gases across a range of 0.5-500 mL/min.
• • NIST traceable calibration
• • Explosion-proof rating for flammable and explosive gases
• • Accuracy of +/- 2% of flow or +/- 0.05 mL/min., whichever is greater
• • Over range warning indicator
• • Auto shut-off feature
• • Use as a bench-top or hand-held unit
• • Ergonomic design and side grips for comfort
• • Measures most gas types*
• • Convenient carrying/storage case included
• • CE certified
• • Uses 2-AA batteries
• • Data output via USB port
• • Re-calibration service available

*This flowmeter is designed to measure clean, dry, non-corrosive gases.

Backed by a 1-year warranty, the Restek ProFLOW 6000 flowmeter will set the industry standard for electronic flowmeters!

Carrying/storage case included with purchase of unit.

Another unbeatable offer from Thames Restek -

£150 OFF All Restek Capillary G.C. Columns until 31^st January 2010

Unsurpassed inertness

An Rxi® column’s inertness allows analysis of active compounds at levels not attainable with other manufacturers’ columns.
Basic and acidic compounds can be analyzed on the same column, often under the same conditions.

Ultra-low bleed

Save time and money through faster baseline stabilization.
With the lowest column bleed in the industry, Rxi® columns improve detection for trace level GC/MS analysis. Ultra-low bleed also reduces conditioning time after instrument maintenance.

Guaranteed reproducibility

Consistency is everything. With Rxi® column technology, we guarantee it: every new column will perform exactly as the column it replaces.

Unmatched performance

Every Rxi® column is held to stringent performance specifications for coating efficiency, selectivity, film thickness, inertness, and bleed. This guarantees you the most reliable columns available anywhere.

New Column Option for Reliable HPLC Separation of Explosives

• Separate all 17 target explosives.
• Eliminate false positives for tetryl and other difficult compounds.
• Eliminate equilibration steps and save time with isocratic analyses.

Reliable analysis of explosives is largely dependent on the selectivity and sensitivity of the analytical column. Analysis by LC often follows EPA Method 8330B, an update of the original method which now incorporates mass spectrometry (MS) as an alternative to ultraviolet (UV) detection. Typically, when analyzing by UV, a C18 primary column with a cyano- or phenyl-based confirmation column is used. However, several compounds can be problematic on these phases, including 2,6-dinitrotoluene and 2,4-dinitrotoluene which may coelute or show poor response with UV detection. Tetryl is another difficult analyte that is susceptible to both heat degradation and false positives on C18 columns. By using columns with different selectivities, analysts can more accurately identify target explosives.
