The Tightest QC Specifications
in the Industry

  • Highest level of column-to-column reproducibility
  • Decreased column bleed for increased sensitivity

The individual bleed specifications represent the difference, in pico amperes of the FID, measured at the upper temperature limit of the column and the isothermal test temperature (generally 110°C to 125°C). J&W strives for the lowest bleed GC columns in the industry.

The specifications for RI represent J&W’s narrow retention index windows. A small number means you get the highest level of column-to-column reproducibility.

Plates per meter is a measurement of the resolving potential for a GC column. J&W publishes the minimum plates specifications that a column must have before it can become a J&W capillary column.

All J&W columns are individually tested and must live up to our stringent QC requirements.
