InertSustain PFPA pentafluorophenyl-modified column designed for enhanced separation of structurally similar compounds through multiple retention mechanisms, including π-π, dipole, and hydrogen bonding interactions.
InertSustain PhenylA directly bonded phenyl group gives the InertSustain Phenyl column unique reversed-phase selectivity, ideal for separating polar compounds and structural isomers via π-π and hydrogen bonding interactions.
InertSustain PhenylhexylA phenylhexyl-bonded column that offers complementary selectivity to traditional alkyl-chain columns, providing high inertness, reproducibility, and low back pressure.
LD249 Gas Leak DetectorCompact, easy-to-use leak detector with thermal conductivity sensor for fast, accurate gas detection. Replaces the LD239.
FM4: Air Sampler for PFASLow-volume air sampler for PFAS enabling comprehensive analysis of both gas and particle phases in a single sampling using stage-optimized materials.
OralChroma Halitosis Measuring DeviceHigh-precision breath analyzer using gas chromatography to quantify VSCs in 4 minutes — fast, reliable, and maintenance-free.
GL Sciences offers silica-based SEC columns featuring diol phases for the separation of large molecules in both aqueous and organic modes. Our portfolio includes both Inertsil and ProteoSil SEC columns, available in multiple pore sizes to support a wide molecular weight range. These columns provide high resolution and operate at higher pressures than traditional polymer-based SEC columns.
Inertsil Diol column has characteristics of dihydroxypropyl group bonded phase. It shows unique selectivity normal phase mode. The separation mechanism of diol column is featured by hydrogen bonding interactions between diol groups and polar compounds. Diol columns provide an alternative selectivity to silica columns often with increased retentivity. Selectivities of Inertsil ...
Inertsil WP300 Diol has dihydroxypropyl group bonded to silica gel with pore size 300 Å and is capable of analyzing large molecules. Like Inertsil Diol, Inertsil WP300 Diol can be used for both aqueous SEC (Size Exclusion Chromatography) and organic SEC. Also, as a diol column, Inertsil WP300 Diol can be used in both normal phase and reversed phase mode.
As the pore size of ...
Equipped with dihydroxypropyl groups bonded to silica gel, the ProteoSil 300-SEC column is suited for the analysis of large molecules and can be used as a dial column.
Constructed for aqueous size-exclusion chromatography, the ProteoSil 100-SEC can handle higher operating pressures and is suitable for series column configurations.
