  202200High capacity oxygen purifier for long term protection of capillary column stationary phases against oxidation at GC operating temperatures. It is also recommended for packed column carrier gases and is effective for removing sulfur compounds, such as hydrogen sulfide and mercaptans. The Model 1000 is intended for use with non-oxidizing gases such as He, Ar, N2, H2 or CH4, containing less than 1% oxygen. The Model 1000 Oxygen Purifier is a high-pressure metal cylinder filled with 500 cc of active oxygen adsorbent. The adsorbent binds covalently with oxygen; no gas is generated from this reaction. It is delivered in the active state, filled with high-purity helium. It is ready for use, but we recommend that the purifier be purged with the gas you will be using. Regeneration: The Model 1000 may be regenerated. Factory regeneration service is recommended, see item number 202204. *Note that sulfur compounds permanently poison the adsorbent.LIÊN HỆ:Email: info.esteco@gmail.comĐiện thoại: +84 979 987 250..

  202332This a high-pressure metal cylinder filled with 500 cc of activated charcoal, one of the most effective adsorbents for organics and hydrocarbons. Removes C5 weight and heavier hydrocarbons from inert gases, air, or hydrogen to low ppb levels. It is also recommended for use with purge and trap apparatuses, and with GC carrier gases for trace analyses. Highest efficiency is obtained using flow rates below 500 cc/min. Frits in each end prevent fines from entering the gas stream. The Model 300 is delivered filled with high-purity helium; it should be purged before use with the gas you will be using. LIÊN HỆ:Email: info.esteco@gmail.comĐiện thoại: +84 979 987 250..

  202212D-BThe ZPure CO2 Filter removes carbon dioxide from inert gases, He, Ar, N2, H2, and clean dry air (CDA) to low ppb levels. The filter functions by consuming carbon dioxide in a reaction with highly-dispersed NaOH on a silicate support. The reaction produces water which remains adsorbed in the purifier. In highly critical applications consideration should be given to using an additional moisture trap after the CO2 Filter as a safety measure. It is available in 4 sizes of stainless steel cylinders ranging from 130 cc to 750 cc. The ZPure CO2 Filter is available with standard compression fittings and quick connect fittings offered in ¼” and 1/8” brass and stainless steel, or metal push-to-connect fittings in ¼” and 6 mm for plastic tubing. LIÊN HỆ:Email: info.esteco@gmail.comĐiện thoại: +84 979 987 250..
