Chemex (surface water) ICP (calcium) – d.l.= 0.5

Chemex, surface water; ICP (calcium) – detection limit is 0.5 ppm

General Methodology:

Calcium in waters was determined by inductively coupled plasma emission spectroscopy.  An aliquot from the sample bottle was transferred to a separate container and aspirated directly into the ICP spectrometer (Instrumentation Laboratory model 200).  Measurements were made at 317.9 nm.  The instrument was calibrated with aqueous standards.
