Convenient Measurement of Water by GC with Watercol™ Series Columns

The Watercol™ capillary GC columns allow the qualitative and quantitative analysis of water in a variety of matrices, by GC, eliminating the need for special testing for water. This is a revolutionary new column that is taking the industry by storm, causing analytical chemists to say, "It's magic!”

The Watercol™ column, coupled with the appropriate detector, has reliably and reproducibly measured water concentration in a variety of matrices from levels down to 0.5 ppm up to 99+% water. Used with Shimadzu's Nexis GC-2030 Trace Moisture Analysis GC/BID for sub-ppm levels, and with a Thermal Conductivity Detector (TCD) for up to 99+% water, you can achieve excellent water retention, separation and peak shapes.

These Revolutionary Columns Help You Save Time & Money

• Analyse trace levels of water & organics with one easy GC method
• Eliminate the hassle of special testing for water
• Obtain reliable and reproducible results

Proven Application Areas:

• Water in Liquid Petroleum Products
• Water in Alcohols
• Water in Gasoline
• Water in Ethanol
• Water in Solvents
• And many more...

The Watercol™ columns contain innovative ionic liquid stationary phases that produce a sharp peak shape for water. Narrow peak widths and optimal peak heights are also produced for many other polar analytes. Therefore, these columns are suitable for many applications where:

• Water as an analyte: it can be integrated and quantified
• Water as the injection solvent: because water does not tail, it does not interfere chromatographically with other analytes

An example highlighting the use as water as an analyte is the analysis of water in gasoline (spiked) on Watercol™ 1910. You can qualitatively and quantitatively measure BTEX components and water on one column with one easy GC method.

An example highlighting the use of Water as the injection solvent is the analysis of a 7-Component Solvent Mix in Water on Watercol™ 1910. You can clearly see all the solvent peaks as well as a sharp peak for water, allowing easy analysis of the analytes of interest.

A new test method work item (WK59649) has been proposed to ASTM with the Trace Moisture Analysis GC/BID and the Watercol™ column for the Determination of Water in Liquefied Petroleum Gas (LPG) through the ASTM D02 H00 committee. Be on the lookout for the official method once it is approved by ASTM!
