Analyst's Comments
#1 It should be noted that the C7-C9 result for sample 2304043.1 has been adjusted due to the discovery of a laboratory
artefact that is produced from the extraction solvent by samples with elevated pH levels.
#2 It should be noted that the C7-C9 result for sample 2304043.2 has been adjusted due to the discovery of a laboratory
artefact that is produced from the extraction solvent by samples with elevated pH levels.
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 simple 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. A detection limit range
indicates the lowest and highest detection limits in the associated suite of analytes. A full listing of compounds and detection limits are available from the laboratory upon request.
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.
Dates of testing are available on request. Please contact the laboratory for more information.
Samples are held at the laboratory after reporting for a length of time based on the stability of the samples and analytes being
tested (considering any preservation used), and the storage space available. Once the storage period is completed, the
samples are discarded unless otherwise agreed with the customer. Extended storage times may incur additional charges.
This certificate of analysis must not be reproduced, except in full, without the written consent of the signatory.
