KANSO CO.,LTD.

Reference Material for Nutrients in Seawater(RMNS): Certified Reference Material
ISO 17034 (Accreditation No. ASNITE 0052 R)

KANSO is the producer of RMNS and accredited under the Accreditation System of National
Institute of Technology and Evaluation (ASNITE) as a CRM producer since 2011.

For the measurements of seawater nutrients (nitrate, nitrite, phosphate,silicate), RMNS will help assessments of measurement repeatability andaccuracy, comparability of collected data, and the quality management ofmeasurement data by including RMNS with sample measurements.

Are you not troubled?
 Differences in the last year and this year's data.
 Comparison of measurement data among analysts.
 Dispersion of measurement data.
 Systematic error caused by differences in laboratories.
 Accuracy management of measurement data.
 Maintenance check with the analysis equipment.

Japan Patent No. 3477468, 4459752, and 5705574
Korea Patent No. 10-1507432
US Patent Publication No. US-2013-0305660-A1

Characteristics
 Nutrients in seawater are contained in 100 mL-polypropylene bottle.

Target nutrients are nitrate, nitrite, phosphate, and silicate (about 90 mL sample per bottle).

 Uses 100% natural seawater and poison is not added.
The matrix of seawater is maintained because there is no additive.
Poison such as mercury is not added.

 Nutrients concentration range is covered from low to high levels.
The range of concentrations in the ocean can be covered.

 Can be measured immediately with an auto analyzer.
After opening RMNS, there is no need for dissolution and/or dilution step.
Can be measured by putting in a sample cup.

 A custom order by the lot unit is possible.
The production of 200 to 2,500 bottles per lot is possible.
If the seawater of the object sea area (for instance, theArctic, the North Atlantic, the equatorial regions, coast bay,etc.) can be sent to our facility, we will complete the rest ofthe processes and deliver the goods.
For more details about RMNS and information on current
available lots in stock, please contact RMinfo@kanso.co.jp.

RMNS: Reference Material for
Nutrients in Seawater

RMNS is most suitable for Continuous Flow Analysis
Continuous Flow Analysis (CFA) can measureseveral analytes at the same time.
With just one bottle of RMNS, quality control offour nutrients can be done simultaneously.
RMNS is a CRM with excellent cost performancefor seawater nutrients measurements.

RMNS mentioned in GO-SHIP Repeat Hydrography Manual (2010)
An international nutrients analysis manual was revised in August, 2010, and methods
for measurement using RMNS was suggested in the following manual: GO-SHIP
Repeat Hydrography Manual: A Collection of Expert Reports and Guidelines,
IOCCP Report No. 14, ICPO Publication Series No. 134, “Recommendations for theDetermination of Nutrients in Seawater to High Levels of Precision andInter-Comparability using Continuous Flow Analysers”.
