產(chǎn)品特點(diǎn):

Dedicated for Biodiesel Analysis
• Complete set of biodiesel columns for full compliance and ease-of-use
• UltiMetal™ technology provides high accuracy and longevity
• Designed and pre-tested for complete confidence in results

Select Biodiesel columns address the key challenge of good column lifetime when operating at very high temperatures up to 400 °C. Although traditional fused silica can be used, high temperatures often mean shortened column lifetimes. By using an UltiMetal column with an ultra-stable stationary phase, results are
more consistent and column breakage is a thing of the past.

Select Biodiesel columns are offered with a pre-coupled retentiongap that is leak tested prior to shipment, making life much easier for the operator. This short piece of tubing not only enhances the analytical separation but also dramatically simplifies automation when using the column with a column inlet as specified in the standard methods.
