Types of materials analysed include

• aqueous samples with saline matrix
• borehole monitor samples
• environmental waters
• ground waters
• stream waters
• synthetic and experimental fluids

The analytical techniques available are:

• inductively coupled plasma-atomic emission spectromety (ICP-AES) for major and trace cations
• ion chromatography (IC) for major and trace anions
• organic carbon analyser for non-purgeable organic carbon (NPOC)
• potentiometric titration for pH and alkalinity
• potentiometry for electrical conductivity
