Identification and optimization of the chemical, series of chemicals or bio-molecule that will interact with the target using impartial, expert opinion about the best equipment, services and the latest techniques
The Perfect Combination of Low Bleed, Thermal Stability, and Easy Puncturability!Molded Thermogreen LB-2 septa are manufactured from high quality, low bleed material using the same exclusive LB-2 rubber formulation that chromatographers are accustomed to using. The difference is that molded septa, unlike traditional die-cut septa, offer easier installation and better sealing inside the injection port. This is because our liqui…
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…

High Capacity Gas Purifiers (Remove Moisture and Oxygen)The best purifier choice for removing moisture and oxygen from carrier gas streams is our High Capacity Gas Purifier. It consists of three parts:• Clam-shell oven• Replaceable heating elements• Replaceable converter tube.A convenient starter kit contains all three items for new installations.
Supelcarb® is Back by Popular Demand!Supelco® is pleased to welcome the Supelcarb HC Hydrocarbon trap back to our line of in-line gas purifiers! Supelcarb adsorbent has the greatest trapping ability of hydrocarbons per gram of adsorbent (twice that of activated charcoal). These traps are the best traps available for removing hydrocarbons and other organics from carrier, fuel, air and other gas streams.
Specialty In-Line Purifier for GC-MS HeliumThe most sensitive GC-MS instruments require a steady stream of ultra-high purity (99.99999%) helium for optimal performance. 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…
