一般說明

当进入气体中的级别不超过 10 ppm 时，除氧催化剂可将氧降低至 2 ppb 以下。因为催化剂是涂在分子筛上的，所以这个捕集阱也可以除去水蒸气。

尺寸：
  • 120 cc Trap：11 1/8 in.(28.2 cm) 长 x 1 3/8 in. (35 mm) 直径
  • 750 cc Trap：16 1/2 in.(41.9 cm) 长 x 2 5/16 in. (59 mm) 直径
  • S-Trap：7 1/2 in. (19 cm) 长 x 5 9/16 in. (14.1 cm) 宽 x 1/2 in. (13 mm) 直径 [ 总床长 = 19 3/4 in.(50.2 cm)；延长的床长度确保气体和吸附剂之间的长期联系，并提供更大的工作能力 ]

應用

采用 5A 分子筛湿气清除装置和 Supelpure -O 氧/湿气清除装置串联净化乙烯。[1]

Questions

1–3 of 3 Questions  

  1. Is the S-Trap included with purchase of either the 750cc or 120cc trap? What style of fitting do the traps have?

    1 answer

    1. The S-Traps are not included with any of the Oxygen/Moisture traps and have been discontinued. These traps have a 1/8 inch Swagelok fitting.

      Helpful?

  2. What is the expected lifetime of this mositure trap?

    1 answer

    1. Product No. 22449 has a stated life of 6.5 gas cylinders. This stated life is based on 9 in. x 51 in. cylinders (218 cubic feet) of carrier gas containing 50 ppm of contaminants supplying one chromatograph with two capillary columns. To correct for other volumes of gas per cylinder, multiply this stated life (cylinders) by the number of cubic feet in the cylinders, then divide by 218.

  3. Regarding the Supelpure™-O Oxygen/Moisture Trap 120 cc, what flow rate is suitable for this device? And is removal efficiency dependent on temperature? At last, could I use this device to remove ppm level oxygen contaminations in pure CO2 as well?

    1 answer

    1. Please see below for responses to each question submitted.

      1. What flow rate is suitable for this device?
      The maximum flow rate for the Supelpure™-O Oxygen/Moisture Trap - 22449 is 250 ml/minute. The pressure setting on the incoming carrier gas tank depends on what type of analysis is being done (packed or capillary, isothermal or temperature programmed method, etc.) The typical recommendation for GC applications is that the pressure be at least 20 psi higher than that achieved during the analysis - preferably 40-50 psi higher.

      2. Is removal efficiency dependent upon temperature?
      Unless the GC maintains constant pressure, as the temperature goes up, resistance/increased back pressure causes the flow rate to drop.

      3. Is this device able to remove ppm level oxygen contaminations in pure CO2
      The capacity for these traps will not vary considerably with changes in the inlet concentration of O2. At high levels of O2, the efficiency may be impacted. Oxygen is reduced to less than 0.5 ppm when the level of the incoming gas does not exceed 10 ppm. Since this trap can only remove oxygen and moisture, it can be used to remove oxygen from the CO2 gas stream as well.
