Instrumentation

I welcome interest from other groups interested in using the facilities.

Seawater DIC chemistry characterisation:

In my lab I have an Apollo SciTech AS-C3 fitted with a LiCOR NDIR LI-7000 CO₂ analyser for determination of total dissolved inorganic carbon (typical precision = 0.1%, 1 sigma). I have a Metrohm 848 Titrino plus fitted with an Aquatrode pH sensor for total alkalinity analysis (typical precision ≈ 3-4 μmol kg^‑1). We calibrate both instruments with seawater CRM from Andrew Dickson (UCSD) or with Na₂CO₃ standards, depending on the application.

Marine organism culturing:

The St. Andrews pCO₂ controlled culturing system allows the culturing of organisms at tightly controlled seawater pCO₂, temperature and salinity.
