Specific quantitation limits <br />are highly matrix dependent. The quantitation limits listed herein <br />are provided for guidance and may not always be achievable. Any <br />questions or comments regarding this report should be directed to <br />the Organic Laboratory Department, Colorado Department of Health, <br />phone #(303) 331-4728.
