"AAS iCE 3000 Series Chromium content less absorption”
We are using above mentioned Flame AAS in our laboratory. We are analyzing in chromium content using Acetylene and Nitrous oxide gas absorption level is very less. Normally 0.4 absorption in 5 ppm but we are getting only 0.045 absorbance level. We are checking with standard solution the standards are no deviation. we are consulting with service person they told Nitrous oxide and Acetylene gas combination flame will be a "Red cone formation". But we are getting blue mixed with yellow colour.This is the reason for lesser absorbance or any other reason. Please help me.
