Astec® CHIROBIOTIC® V Chiral HPLC Column 11023AST
eCl@ss: 32110501 NACRES: SB.52 General descriptionNeutral molecules, amides, acids, esters and amines show considerable enantioselectivity on these vancomycin-based CSPs. A wide variety of secondary and tertiary amines have been separated on the CHIROBIOTIC® V in the polar ionic mode. The CHIROBIOTIC® V has demonstrated many of the separation characteristics of protein-based stationary phases, but with exceptional stability and much higher sample capacity. Some chiral analytes have been resolved that have not been reported separated on any other chiral stationary phase. CHIROBIOTIC® V and V2 differ in their bonding chemistry the pore size of the support particle, giving them different selectivity and preparative capacity.- Bonded phase: Vancomycin
- Operating pH range: 3.5 - 7.0
- Particle diameter: 5, 10 or 16 µm
- Pore size: 100 (CHIROBIOTIC® V) or 200 (CHIROBIOTIC® V2)

Astec® CLC-D Chiral HPLC Column 53023AST
eCl@ss: 32110501 NACRES: SB.52 General descriptionCLC columns use the copper ligand concept described by Davankov to effect enantiomer separation (1). The method uses a small, chiral bidentate ligand attached to the silica surface and a copper sulphate-containing mobile phase. The copper ions coordinate with the chiral selector on the stationary phase and carboxylic acid functional groups on the analytes to form transient diastereomeric complexes in solution. The technique also has the advantage of giving small acids with no UV chromophore a strong 254 nm signal. CLC columns are ideal for analysis of hydroxy acids, like lactic, malic, tartaric and mandelic acids, amino acids, other amines and bi-functional racemates, like amino alcohols. Proline and aspartic acid are particularly suited for low-level detection on the CLC column since the copper complex is detected at 254 nm UV. Both can be resolved on the CLC-D or CLC-L in 5 mM CuSO4 with the usual reversal of elution order from the CLC-D to CLC-L. In theory, any analyte that can complete the coordination with the copper ion can be resolved. Two versions of the column provide elution order reversal. On the CLC-D column, the L enantiomer generally elutes before D, with the exception of tartaric acid. The reverse is true on the CLC-L column where D elutes before L.
Features:- Separates -hydroxy carboxylic acids, amino acids and other -bifunctional compounds
- High selectivity with simple mobile phases
- Copper complex gives strong UV 254 nm signal
- Simple reversal of elution order, CLC-L vs. CLC-D
- Excellent reproducibility

Менеджер по работе с клиентами
С 2010 года мы поставляем оборудование с заводов Европы. Берем на себя все — от подбора оборудования до внедрения на предприятии
Все сотрудники имеют высшее образование, закончили ведущие химические вузы страны, такие как РХТУ им Менделеева.
У большинства компаний срок ожидания составляет 10-12 недель.
Оборудование хранится на сухом отапливаемом складе, где поддерживается ровная температура.
Работаем с PonyExpress и Деловыми линиями. Вы также можете выбрать свою транспортную компанию или забрать товар со склада в Москве.
В случае любых неполадок за свой счет выполним ремонт в сервисном центре или на заводе-изготовителе. Или бесплатно заменим прибор на новый.
Производим пуско-наладку оборудования, валидацию, обучение сотрудников. Если нужно, привлекаем инженеров с заводов- изготовителей.
