Summary of Methods
The following table(s) gives a brief description of the methods used to conduct the analyses for this job. The detection limits given below are those attainable in a relatively clean matrix.
Detection limits may be higher for individual samples should insufficient sample be available, or if the matrix requires that dilutions be performed during analysis.
Unless otherwise indicated, analyses were performed at Hill Laboratories, 28 Duke Street, Frankton, Hamilton 3204.

These samples were collected by yourselves (or your agent) and analysed as received at the laboratory.
Samples are held at the laboratory after reporting for a length of time depending on the preservation used and the stability of
the analytes being tested. Once the storage period is completed the samples are discarded unless otherwise advised by the
client.
This certificate of analysis must not be reproduced, except in full, without the written consent of the signatory.
