Receipt

Twenty-two samples were received on 2/7/2019 9:00 AM; the samples arrived in good condition, properly preserved and, where required, on ice. The temperature of the cooler at receipt was 1.0º C.

LCMS

No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.

Organic Prep Method(s) 537 DW: The following samples were observed to be a yellow color after elution: YK-10 (320-47461-10), YK-11

(320-47461-11), YK-12 (320-47461-12), YK-13 (320-47461-13), CO-01 (320-47461-15) and CO-02 (320-47461-16).

Method(s) 537 DW: Sample CO-03 (320-47461-17) was centrifuged prior to extraction due to having sediment.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
