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 high-performance PFP and Phenyl columns designed to enhance selectivity through π–π interactions, dipole effects, and steric recognition. InertSustain PFP provides strong retention for polar and basic compounds, while InertSustain Phenyl and Phenylhexyl phases offer complementary selectivity for aromatic analytes and structural isomers. Ideal for resolving challenging separations that C18 columns can’t address. Available in multiple particle sizes and bonded chemistries for flexibility across reversed-phase applications in pharma, food safety, and environmental testing.
InertSustain PFP columns are bonded with pentafluorophenyl groups to our newly developed ES silica gel, which delivers unique separation patterns with excellent peak shape and sensitivity. The chromatographic difference stems from the fact that the PFP phases provide interactions such as π-π, dipole, hydrogen bonding, and ionic interactions unlike conventional PFP columns.
InertSustain Phenylhexyl columns are bonded with phenylhexyl groups, which employs a phenyl ring with a hexyl (6- carbon) linker and is densely bonded to our newly developed ES silica gel delivering complementary selectivity to straight alkyl-chain columns, but with industry leading inertness, lot-to-lot reproducibility and low back pressure.
InertSustain Phenyl delivers an extremely unique reverse phase characteristics that are critical to resolving compounds that could not be separated on a C18 or C8 phase. InertSustain Phenyl provides not only pi-pi interactions, but also hydrogen bonding secondary interactions, which results in retaining polar compounds at the same time. As the phenyl groups are directly bonded ...
Just like InertSustain Phenyl, Inertsil Ph-3 has phenyl groups directly bonded to the silica gel which provides pure reverse phase characteristics that are critical to resolving highly polar compounds like acidic and basic pharmaceuticals. The near perfect phenyl phase coverage on this material results in symmetric, narrow peaks for even the most polar compounds while using ...
Inertsil Ph has phenethyl groups bonded to silica gel which offers weak pi-pi interactions. As it is modified with phenethyl groups, hydrophobic interactions between alkyl chain and analytes play an important role in separation as well as π-π interactions. To change the selectivity or elution pattern drastically, InertSustain Phenyl is recommended as it provides strong pi-pi ...
