For preserved samples, please <br />provide either a non -preserved sample (1 ) or the electrical conductivity prior to <br />acidification. <br />Note: All solid samples should be collected in stainless steel sleeves, brass sleeves or in glass <br />jars all with teflon -lined caps and 4-8 oz. capacity. Ali solid samples should be kept cool at 4 <br />C. <br />
