Column, LC, Shim-pack GIST-HP Guard Column C18-AQ, 1.9um, 1.5x10 with Cartridge (2pcs) and Holder Excellent Retentivity of Highly Polar Compounds. Shim-pack GIST C18-AQ achieves strong retention of hydrophilic highly polar compounds compared to general C18 columns, while maintaining high inertness and durability in highly or 100% aqueous mobile phases. Shim-pack GIST C18-AQ is also able to reduce the absorption of basic and acidic compounds and achieve superior peak shapes in the analysis of metal complexes. Bonded Phase Octadecyl Groups, Particle Size 1.9 ?m, 3 ?m, 5 ?m, Pore Size 10 nm, Surface Area 350 m2/g, Carbon Loading 13 %, End-capping Yes, pH Range 1 to 10, USP Code L1.

Vial: 75.5 x 22.5mm, clear glass, 1st hydrolytic class, DIN crimp neck, long neck, round bottom. Cap: 20mm combination seal, Aluminum, plain, center hole. Septum: silicone white/PTFE beige, 45° shore A, 3.2mm. Replacement for 220-97331-34.
Standards, LC, 6 Cpds (CBDA, CBD, CBG, CBN, THCA-A, Delta-9-THC) in ACN (1mL x 500 ug/mL ea), CRM Certified reference material for research and forensic applications using HPLC-UV, GCMS, or LC-MS/MS. Included are Delta9-THC, THCA-A, cannabidiol (CBD), cannabidiolic acid (CBDA), cannabinol (CBN), and cannabigerol (CBG). Supplied in an amber ampule in which the headspace has been purged with argon. This mixture is provided as a DEA exempt preparation. Must be refrigerated upon receipt.
Column, LC, Shim-pack GIST Guard Column Phenyl-Hexyl, 5um 1.0x10 with Cartridge (2pcs) and Holder Alternative Selectivity to C18 Columns. Shim-pack GIST Phenyl-Hexyl columns are bonded with a phenyl ring together with a hexyl (C6) chain, which provides complementary selectivity to straight alkyl-chain columns due to its ?-? interactions and hydrophobic interactions. Furthermore, Shim-pack GIST Phenyl-Hexyl maintains the same ultra-high inertness, wide pH range and high durability as the Shim-pack GIST C18, achieving stronger retention than other phenyl columns as well as reducing or eliminating adsorption of polar compounds. Bonded Phase Phenylhexyl Groups, Particle Size 3 ?m, 5 ?m, Pore Size 10 nm, Surface Area 350 m2/g, Carbon Loading 9 %, End-capping Yes, pH Range 1 to 10, USP Code L11.
