Remarks

Cm Remarks

A certified reference material, NIMD-02, was developed primarily for mercury speciation analysis. We collected low-concentration urine and made 1000 sets (per set: 4 mL x 4 bottles). Extended uncertainty was estimated taking into account sample uniformity, long-term and short-term stability, and characterization from measurements made by the collaborative laboratory. A short-term stability test for 4 weeks at 37°C was conducted to consider overseas shipment. A temperature indicator for 37°C is enclosed with the actual product. Immediately after receiving the product, store in a clean place at less than −20°C and avoid light.
