MiPT – Metrohm intelligent Partial Loop Technique
Summary
Calibration of lithium, sodium, ammonium, zinc, potassium, magnesium, and calcium using the partial loop technique and cation chromatography with direct conductivity detection. This technique allows a calibration range of 1:100 (e.g. 1 μg/L to 100 μg/L corresponding to 2 μL to 200 μL injected volume) out of 1 calibration solution. Applying the full range of partial loop injection to the samples one calibration covers a sample concentration range of 1 to 10'000 e.g. 2 μL of a 10 mg/L solution corresponds to the highest calibration level (100 μg/L) while 200 μL of a 1 μg/L solution corresponds to the lowest calibration level.
