Lancaster Laboratories Explanation of Symbols and Abbreviations The following defines common symbols and abbreviations used in reporting technical data: N.D. none detected BMQL Below Minimum Quantitation Level TNTC Too Numerous To Count MPN Most Probable Number IU International Units CP Units cobalt-chloroplatinate units umhos/cm micromhos/cm NTU nephelometric turbidity units C degrees Celsius F degrees Fahrenheit Cal (diet) calories Ib. pound(s) meq milliequivalents kg kilogram(s) g gram(s) mg milligram(s) ug microgram(s) I liter(s) ml milliliter(s) ul microliter(s) m3 cubic meter(s) fib >5 um/ml fibers greater than 5 microns in length per ml < less than—The number following the sign is the limit of quantitation, the smallest amount of analyte which can be reliably determined using this specific test. > greater than PPM parts per million —One ppm is equivalent to one milligram per kilogram (mg/kg), or one gram per million grams. For aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter(mg/I), because one liter of water has a weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter of gas per liter of gas. ppb parts per billion Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight basis concentration to approximate the value present in a similar sample without moisture. U.S. EPA data qualifiers: Organic Qualifiers Inorganic Qualifiers A TIC is a possible aldol-condensation product B Value is <CRDL, but ?:IDL B Analyte was also detected in the blank E Estimated due to interference C Pesticide result confirmed by GC/MS M Duplicate injection precision not met D Compound quatitated on a diluted sample N Spike amount not within control limits E Concentration exceeds the calibration range of S Method of standard additions (MSA) used the instrument for calculation J Estimated value U Compound was not detected N Presumptive evidence of a compound (TICs only) W Post digestion spike out of control limits P Concentration difference between primary and Duplicate analysis not within control limits confirmation columns >25% + Correlation coefficient for MSA <0.995 U Compound was not detected X,Y,Z Defined in case narrative Analytical test results for methods listed on the laboratories' accreditation scope meet all requirements of NELAC unless otherwise noted under the individual analysis. Tests results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological analysis is the collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved, the test results will be meaningless. If you have questions regarding the proper techniques of collecting samples, please contact us. We cannot be held responsible for sample integrity, however, unless sampling has been performed by a member of our staff.
