Purged analyzer buildings

Figure 2-23 Typical pressurized and purged analyzer buildings found in chemical plants handling flammables.

Division 2/Zone 2, will provide increased design flexibility, lower cost to build, simpler maintenance, optimum safety and suitability for the widest range of applications and requirements. Division 1 (Zone 1) will allow the use of analyzer optical windows, as well as dynamic and static elastomer seals, without the need for additional electrical protechon methods such as purging, continuous dUuhon or pressurization. 

The CVs in Ar-purged 1M LiCl + HCl electrolyte (pH 1) of another series of POMOFs containing POM building blocks connected by btc-linkers showed two redox waves characteristic of the reversible oxidoreduction of Mo centers. The compound (tba)3[PMo 8Mo 4036(OH)4Zn4](btc)4/3-6H20 (labeled e(trim)4/3) was analyzed, as well as two other compounds (labeled E2(trim)2 and [8(trim)] o) showing different stoichiometries and topologies. The redox waves were centered at ca. +0.12 V versus SCE for e(trim)4/3 and e2(trim)2 and -0.1 to -0.12 V versus SCE for 82(trim)2 and 8(trim)4/3.
