Description
The isotopic compositions of the natural potassium chloride sample NIST SRM 999b, and the isotopically enriched material GSC K-40 that is used in an ongoing study of the half-life of 40K by decay counting, were determined using total evaporation thermal ionisation mass spectrometry (TE-TIMS) and incipient emission thermal ionisation mass spectrometry (IE-TIMS). Both methods were comprehensively calibrated for precision and accuracy by multiple analyses against gravimetrically prepared synthetic...[Show more]
