Abstract

The comparison experiment results of the standard seawater (SSW) were presented for batches P90, P100, P104, P106, P108 P111, and P112. This work shows that the SSW batch-to-batch agreement was recently improved. The adjusted mean differences relative to the mean of SSW batches P91 to P102 (Mantyla 1987) ranged from −0.6×10−3 to 0.8×10−3 for the SSW batches of P100, P104, P106, P108, P111, and P112.
