Ultra-low bleed silicones for septa promote analytical purity and prevent ghost peaks on chromatographs. To avoid septum bleed, Specialty Silicone Products (SSP) uses only platinum-cured silicones. When requested, a batch of septa can be analyzed in our QC Lab by GC-MS and a copy of the test report can be sent with your order.
By removing excess siloxanes, SSP reduces potential contaminants that could show up in mass spectrometry (MS) during gas [...]
Specialty Silicone Products (SSP) uses platinum-cured silicones to produce septa that are ultra-clean for analytical purity. Compared to peroxide-cured silicones, our platinum-cured elastomers are more inert and less likely to interact with your samples. Platinum-curing is more expensive, but our platinum-cured silicones don’t contain byproducts that cause contamination by leeching or bleeding.
Silicone Curing Systems
Silicones are formed into solids by curing or [...]
Specialty Silicone Products (SSP) is pleased to introduce a new on-line resource for members of the laboratory diagnostic, environmental testing, pharmaceutical, and chemical packaging industries. SSP’s Septa Blog is the place to learn about septa, septum cap assemblies, and cap mats for gas chromatography (GC), liquid chromatography (GC), and other applications that require analytical purity.
The initial entries in this new blog will describe the differences between [...]
