Solution
Using Trial and error set correct
ignition gas flows (plasma and
auxiliary) for thinner air at higher
altitude
Replace SSRF Control PCA
Instrument warm up for 4 hours
Recalibrate Instrument

Adjust
Pulsations due to low pump
speed - Change
Crimped or damaged pump
tube - Change
Uptake delay time too short for
sample uptake tubing length
(first reading low). - Increase
Increase Delay time to align with
sample tube length
