Supelco provides high quality derivatization reagents for acylation.Acylation, an alternative to silylation, allows the conversion of compounds with active hydrogen such as -OH, -SH, and -NH into esters, thioesters and amines, respectively. A very popular example of this method is the insertion of perfluoracyl groups to enable electron capture detection (ECD). Carbonyl groups adjacent to halogenated carbons enhance the ECD res…

Supelco provides high quality derivatization reagents for akylation and esterification.Alkylation is the replacement of the active hydrogen in R-COOH, R-OH, R-SH, R-NH, R-NH2, R-CONH2, R-CONH-R′ with an alkyl group, or sometimes an aryl group.Esterification is the first choice for derivatization of carboxylic acids and other acidic functional groups. Acids are reactive compounds, and are too polar to be well separated by gas c…

To achieve this level, a specialty purifier is required. These purifiers contain multiple adsorbent beds for the removal of all critical contaminants. Additionally, the adsorbent materials are packed into the cartridge under helium to ensure no other gas off-g…

HPLC and FPLC Columns for the Analysis and Purification of Biopolymers.Biopolymers, including peptides, proteins, polynucleotides, and other biodegradable polymers, display a variety of ionic charges and differ in terms of hydrophobicity, size, shape and mass. In addition to these structural (and functional) complexities, an individual biopolymer is typically present at low concentration in samples that contain many similar co…

Cyclodextrin-based DEX and Astec CHIRALDEX phases are stable, high boiling liquids and make effective CSPs for enantiomer separations by GC. The two lines exhibit complementary selectivity.Cyclodextrins are macromolecules composed of 6 or more D(+)-glucose residues bonded through α-glycosidic linkages. They are classified according to the number of glucose residues they contain: α-cyclodextrins (six residues), β-cyclodextrins…

Active Sampling Tubes for Air Monitoring.ORBO sorbent tubes contain two beds of the same selective adsorbent seperated by glass wool or foam, for gas and vapor sampling. The dual-layer or two-bed construction of the tube allows for any sample breakthough to be captured in the smaller back-up bed. Our sorbent tubes contain Supelco′s high quality adsorbents that professionals world-wide trust for their applications. We offer the…

Supelco′s new Low Adsorption (LA) vials are manufactured using a process that decreases the number of hydroxyl groups on the vial′s glass surface, significantly reducing surface activity while improving analytical quantitation and minimizing pH shifts in the sample.This same process also removes unwanted surface metals such as sodium and boron that can contaminate samples and interfere with trace analysis. Unlike other methods…

Our new certified vial, cap and septa products eliminate "fit" and septa contamination concerns associated with other brands.By taking these extra manufacturing and testing steps, we can ensure:• Caps thread properly onto vials, providing an air-tight seal• Syringe needles are not damaged by irregular vial bottom thickness• Minimal contamination from septa impurities.Quality is built into each component of the Supelco certifie…

Cogent Diamond Hydride HPLC Columns are manufactured with TYPE-C™ silica (silica hydride) and a very small amount of carbon on the surface that adjusts the column hydrophobicity to an important level. This makes these columns have unique separation capabilities for scientists working in LCMS, metabolomics, bioanalytical, amino acids, organic acids, carbohydrates, and very polar small molecules.

The Atmospheric Solids Analysis Probe* (ASAP) is a useful tool for the rapid direct analysis of volatile and semi-volatile, solid and liquid samples using atmospheric pressure ionization.The ASAP technique utilizes the heated nitrogen desolvation gas to vaporize the sample and a corona discharge for sample ionization. This allows low polarity compounds not amenable to ESI, APcI and APPI to be ionized with a high degree of sen…
