Pierce™ Dimethylsulfoxide (DMSO), Sequencing Grade Thermo Scientific™ Thermo Scientific Pierce Dimethylsulfoxide (DMSO) is a sequencing-grade preparation with high purity for use in traditional amino acid analyzers and other high-volume applications. This sequencing-grade dimethylsulfoxide is >99.5% pure DMSO. Pierce™Dimethylformamide (DMF), Sequencing grade Thermo Scientific™ Thermo Scientific™ Pierce™ Dimethylformamide (DMF) is a sequencing-grade preparation with high purity and consistent absorptivity properties for use in HPLC and mass spectrometry methods. This sequencing-grade dimethylformamide is specially purified by a proprietary method and tested to ensure... Pierce™ Triethylamine (TEA), Sequencing Grade Thermo Scientific™ Thermo Scientific Pierce Triethylamine (TEA) is a high-purity solvent that is used in certain HPLC protocols, such as weak anion exchange, to resolve certain tryptic peptides on a reverse-phase column. Features of Thermo Scientific Pierce Triethylamine (TEA): • Greater than 99. Pierce™ Trifluoroacetic Acid (TFA), Sequencing grade Thermo Scientific™ Thermo Scientific Pierce Trifluoroacetic Acid (TFA), Sequencing grade is manufactured and tested to meet strict specifications that ensure superior performance for use as an ion-pairing agent in reverse-phase peptide separations. BSTFA Silylation Reagent Thermo Scientific™ Improve GC analysis with Thermo Scientific™ BSTFA Silylation Reagent. The highly volatile byproducts mono(trimethylsilyl)trifluoroacetamide (BSTFA) and trifluoroacetamide elute with the solvent front to ensure excellent chromatographic separations. HMDS (Hexamethyldisilazane) Thermo Scientific™ Thermo Scientific™ HMDS (Hexamethyldisilazane) greatly extends the practical range of GC, improving chromatographic results in the silylation of sugars and related substances. TMSI Silylation Reagent Thermo Scientific™ Employ the strongest silylator available for carbohydrates and steroids with the Thermo Scientific™ TMSI Silylation Reagent. This silylation reagent reacts quickly with hydroxyls and carboxylic acids but not with amines, and is particularly well suited in multiderivatization schemes for compounds... Pentafluorobenzyl Bromide (PFBBr) Alkylation Reagent Thermo Scientific™ Derivatize carboxyl acids, phenols, and sulfonamides for electron-capture detection (ECD) GC analysis with the Thermo Scientific™ Pentafluorobenzyl Bromide (PFBBr) Alkylation Reagent. Reaction times are fast (∼20 minutes). Pierce™ Heptafluorobutyric Acid (HFBA), Sequencing Grade Thermo Scientific™ Thermo Scientific Pierce Heptafluorobutyric Acid (HFBA) is manufactured and tested to meet strict specifications that ensure superior performance for use as an ion-pairing agent. Features of HFBA: • Greater than 99. Methoxamine (MOX) Reagent Thermo Scientific™ Prepare oximes of steroids and ketoacids prior to silylation with the Thermo Scientific™ Methoxamine (MOX) Reagent. It prevents the formation of multiple derivatives when enols are present during silylation, thereby ensuring optimal quantitation. MethElute™ Reagent (TMPAH) Thermo Scientific™ For accurate, sensitive, on-column methylation and detection by GC analysis use Thermo Scientific™ MethElute™ Reagent (TMPAH). It is ideally suited for the quantitative methylation and detection of barbiturates, sedatives, xanthine bases, phenolic alkaloids, and phenytoin, giving a single...
