Especially when the titer of the standard solution because of some factors such as atmospheric moisture penetration, ambient temperature changes may change or alter the molecular sieve, it becomes all the more important and significant. Reagent calibration frequency is mainly dependent on the selection of the titration reagent Xianning zeolite, the stability of different reagents is different Loudi zeolite, additional storage titrant is not absolute seal, it is recommended every day before the titration must be calibrated. Titration sample purification equipment for air, moisture, oxygen-rich, oxygen and nitrogen separation, separation of n-alkanes, net natural gas system, and through a process of selective adsorption of Ganzhou molecular sieve, and branched chain hydrocarbons and from the ring separating n-paraffins, is currently in the industry for a large-scale pressure alkane separation processes, where can be adsorbed on 3A, 4A molecular sieve molecules, can be adsorbed 5A.
