Atlantic Seawater Conductivity Standard
Intro: This filtered natural ocean water has a salinity of 35 and can be used for a wide range of applications, including; field probe calibration/checks, chemical analysis, particle studies and any other applications which require open-ocean seawater.

This filtered natural ocean water (S = 35) may be used in a wide range of applications including field probe calibration/checks, chemical analysis, particulate studies, corrosion testing and any other applications which require open-ocean seawater.

The label value is quoted in salinity and in specific conductance (mS/cm) with a confidence of ± 0.2%.

It is available in packs of 4 x 5 litres or 10 x 500 ml bottles.

Performance Evaluation Samples
Intro: Performance Evaluation (PE) samples are designed to be used as part of an ongoing quality assurance programme. These uniquely coded samples are supplied unknown to the laboratories for analysis.

Performance Evaluation (PE) samples are designed to be used as part of an ongoing quality assurance programme. These uniquely coded samples are supplied unknown to laboratories for analysis. After analysis the laboratory-determined value is sent to OSIL who issue a certificate showing the true value, the analysts' value and any error.

PE samples for salinity, phosphate, silicate, nitrate, nitrite and ammonia are available. Each sample carries a label quoting its unique sample reference number.

The salinity samples are provided in glass bottles (230 ml) and the nutrients samples in 50 ml plastic bottles. The Salinity samples are accurately measured to 0.001 in salinity and comprise of normal open ocean surface seawater. Samples of higher and lower salinity can be supplied on request.

OSIL is certified to ISO 9001/2000 for the preparation and calibration of marine standards.
