The
Tightest QC Specifications in the Industry
•
Highest level of column-to-column reproducibility
• Decreased column bleed for
increased sensitivity
• All J&W Scientific columns are individually tested and must live
up to our stringent QC requirements
We take column manufacturing
seriously and strive to make the best columns possible. And to prove it,
QC for column bleed, retention index window, and plates per meter are
published for our most popular phases and column configurations.
The individual bleed
specifications represent the difference, in pico amperes of the FID
response, measured at the upper temperature limit of the column and the
isothermal test temperature (generally 110°C to 125°C). We strive for
the lowest bleed GC columns in the industry.
The specifications for RI
represent our 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. We publish the
minimum plate specifications that a column must have before it can become
a J&W capillary column.
