▶ 📝 Notes
* Zero air manufacturer: self made, air compressor: KNF and self construction of charcoal and Purafil cartridge, air compressor: N145.2ANE or PM15486-145.2 * This sheet only concerns NO2! * Zero air generator: air compressor with self made charcoal and Purafil cartridge, and CO to CO2 converter * NO2 permeation tube is used as a transfer to link NO2-Instrument (CAPS) to CLD (42i-TL) that is calibrated with NO reference gas. * Gas Standard Concentration and Gas Standard Uncertainty are taken from the scale certificate
