Подготовка и отбор проб

Příprava vzorků отбор проб

Отбор проб газообразных веществ, загрязняющих веществ и пыли может происходить пассивно или активно.

Для активного отбора проб насосов и отбора проб среды , такие как сорбент трубок , мешки для отбора проб, отбор проб головок и картриджей с различными типами фильтров и импингера .

Для пассивных пробников отбора проб с сорбентами.

Ниже приведена таблица с обзором продуктов, предлагаемых для активного и пассивного отбора проб.

Следующая ссылка приведет вас полный обзор продукции для отбора проб .

Подготовка образца

Для образца препарата используется ряд методов, которые используются для сбора, хранения и обработки образца. Наиболее распространенные методы включают в себя:

Многие образцы и лабораторные методы требуют охлаждения или нагревания. Для этих целей, использование этих устройств:

CA Filters

Cellulose Acetate(CA)CA Filters

  • Composition: Mixture of triacetate and diacetate
  • Characteristics:Low static charge and high strhgth
  • Sterilizable: May be repeatedly sterilized without loss of integrity or change in bubble point
  • Clean: 0.1 wt% aqueous extractables
  • Related to MCE membranes: - improved solvend resistance to low molecular weight alcohols - better heat resistance - lower protein binding

Filtration

FiltrationFilter media selection guide

there are many filtration materials used in filtration process. Filtration is mostly used in various applications, like membrane filtration of water or organic samples, syringe filters in HPLC or air sampling of dust aerosol. Table listed belwo shows most commonly used filter media. by clickin on particulate filter material you will find detailed information.

Below listed materials are used for all that in following applications:

  • Pressure filtration
  • Vacuum filtration
  • Syringe filters (mostly in HPLC and UHPLC)
  • Asbestos sampling
  • Dust aerosol sampling
  • Chemical vapours sampling
  • Determination of dissolved compounds
