CHI134 is the reference electrode built for the CHI130 thin layer flow cell, with a polyacetal plastic body that CH Instruments describe as having good mechanical tolerance and chemical resistance. The centre wire is silver and the tip, 4 mm long and 3.4 mm in diameter, acts as the liquid junction through a VYCOR glass frit. The published specification states it is made for organic solvent and suits mild solvents such as acetonitrile, that the electrolyte may be changed for HPLC use, and that the plastic does not stand up to strong solvents such as THF.
CHI132 is the gold working electrode option for the CHI130 thin layer flow cell. It is one of three flow cell working electrode materials CH Instruments publish, the others being glassy carbon as CHI131 and platinum as CHI133.
CHI135 is the 25 mm spacer CH Instruments publish for the CHI130 thin layer flow cell. It is the only accessory in this group listed in packs, the published unit being four per pack.
