  OSHA 多功能采樣管

  本多功能采樣管*的結(jié)構(gòu)使得同時采集氣體與氣膠成為可能。 OSHA原創(chuàng)的方法克服了一些之前采樣方法的不足，所以經(jīng)常涉及到OSHA多功能采樣管（OVS）. 特殊設(shè)計的玻璃管包含有濾芯收集氣膠，雙節(jié)式的吸附區(qū)收集氣體。所有的材質(zhì)都是經(jīng)過證實的*潔凈的，裝于此構(gòu)造中，以保證低背景干擾。采樣通常使用1升/分鐘的流量，以獲得足夠的體積，采樣體積從60 to 480 升. The tubes are then solvent extracted in toluene, acetonitrile, or acetone and analyzed by GC or HPLC using electron capture, nitrogen/phosphorus, flame photometric, or ultraviolet detectors. The specially constructed open glass tube is 75 mm long with a 13-mm outer diameter on the inlet end tapered to 8 mm on the outlet end. To increase the versatility of this design, SKC has expanded the OVS line to include tubes with variations in sorbents and filter combinations.

  Other combinations of sorbents or filters following the OVS tube design are available by special order for research or other specialty uses. Contact SKC Sales with your tube specifications.
