Кат. номер 87472-250ML-F 87472-INTR-F 87472-VAR-F 87472-50ML-F General descriptionAcylation, an alternative to silylation, is the conversion of compounds that contain active hydrogens (-OH, -SH and -NH) into esters, thioesters, and amides through the action of a carboxylic acid or derivative. The presence of a carbonyl group adjacent to the halogenated carbons enhances electron capture detector (ECD) response. Acylation has many benefits:- It improves the stability of compounds by protecting unstable groups.
- It may confer volatility on substances such as carbohydrates or amino acids, which have so many polar groups that they are non-volatile and normally decompose on heating.
- It assists in separations not possible with underivatized compounds.
- Compounds are detectable at very low levels with an ECD.

Lightweight die for Specac® Atlas 15T presses Z803324-1EA
NACRES: SB.32 General descriptionThe Atlas Lightweight Evacuable Pellet Dies have been specifically designed to work with the range of Atlas automatic presses up to a maximum load rating of 25 tons. The dies are also compatible for use with Specacs 15 and 25 ton manual hydraulic presses.
They are well suited for the preparation of solid pellets for study by X-Ray Fluorescence spectroscopy. When many samples are prepared for study, the pyhsical effort required to load and remove an Atlas Lightweight Evacuable Pellet Die into a press is greatly reduced, as the dies themselves are physically smaller and lighter in weight by comparison to the conventional 32mm and 40mm pellet dies.Legal InformationSpecac is a registered trademark of Specac Ltd.ПараметрыТорговая марка Specac Ltd application(s) IR spectroscopy: suitable size 40 mm Узнать цену -

Анна Гловацкая
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.
