Researchers at the British Antarctic Survey (BAS), based in Cambridge, are using the Palintest Photometer 5000 to monitor water quality for aquatic species brought back from the Antarctic
The BAS runs a marine aquarium that recreates sea conditions in the Southern Ocean.
Fish and invertebrates are kept for study, and precise monitoring of their environment is essential.
The marine habitat of the Antarctic contains wildlife which has adapted (in some cases uniquely) to the extreme conditions.
The research helps identify species' response to environmental change and subsequent effects on both the regional and the global environment.
Using the Photometer 5000, researchers analyse nitrate, nitrite, ammonia and pH levels in the aquarium to maintain them at levels found in the Antarctic seas.
The Photometer 5000 is an advanced colorimeter offering a precise means of water analysis.
It is integrated with the Palintest system of analysis and can perform an extensive range of water tests.
After a reagent is added to a sample, the photometer accurately assesses the colour in the test sample and displays a digital readout.
Used in conjunction with a calibration chart, it is universally applicable to a wide range of tests without the need for manual recalibration or for plug-in calibration modules.
The British Antarctic Survey (BAS) is a component of the Natural Environment Research Council.
For almost 60 years it has undertaken the majority of Britain's scientific research on and around the Antarctic continent.
BAS employs over 400 staff and supports three stations in the Antarctic.
The Antarctic operations and science programmes are executed and managed from Cambridge.
