Separations is a fundamental scientific discipline focused on the isolation and purification of components from mixtures. Through techniques such as chromatography, distillation, and filtration, separations scientists separate substances based on their physical or chemical properties. This field plays a crucial role in various industries, including pharmaceuticals, food and beverage testing, environmental science, materials research, and more. Explore how separations techniques enable precise analysis, quality control, and the development of innovative products.
Supelco provides high quality derivatization reagents for silylation.Silylation is the most widely used derivatization technique. Functional groups that present a problem with gas chromatogaphy detection - hydroxyl, carboxylic acid, amine, thiol, phosphate - can be derivatized by silylation reagents. Silylation involves replacement of the acidic hydrogen with an alkylsilyl group, for example, -SiMe3.Silylation derivatives are…
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…

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…
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.
