Featuring Model 5041 Electrometer for low noise Featuring Model 5121 Flame Detector for low noise at high temperature
on Anakrom ABS, 80/90 mesh
Ijarber-Colman's Selecta-System, Series 5000, offers the analyst an extremely flexible system for keeping abreast of a dynamic technology. The system suggested above has the following advantages: High temperature operation to 500 °C with minimum noise level. • Flexibility of carrier gas flow rate ranges allows use of capillary and packed columns — noise level is constant with flows from 1 to 200 cc/min. and flame is operative to 250 cc/min. • Detector noise level is as low as 10~14 ampere under optimum conditions. Closed detector design avoids fluctuations due to drafts. • Easy to operate and clean. Call any of our nation-wide network of Sales and Service Offices, or contact us a t Rockford.
