The following list of available instrumentation in CAL provides possible sample materials in parentheses. Potential analytical outputs and associated minimum detection limit (MDL) values are for analysis of water samples and measured in mg L-1 unless otherwise noted.

Measures for pH and conductivity can also be determined. For soil samples, an Orion portable pH meter (model 250A) with a Thermo Scientific Orion pH probe is used. For water, an Orion Research digital pH meter (model 611) with a Broadley James pH probe is used. Conductivity measures are determined using an Orion (model 122) conductivity meter.
