Abstract

See full text

A chromatographic device including a coated metallic frit is disclosed. The coating is provided over the fluid exposed surfaces of the frit, thereby covering metallic surfaces to prevent interaction with an analyte in the flowstream. This technology relates to the use of a vapor deposition coated frit together with an uncoated frit in a liquid flow path for improved chromatography. More specifically, this technology relates to liquid chromatographic devices for separating analytes in a sample having a single coated frit within an uncoated metallic fluidic flow path (i.e., the column tube or channel is formed of stainless steel, titanium (pure or alloyed), or some mixture of stainless steel and titanium) and does not include the coating applied to the frit.
