Transcript of Midwest Laboratories, Inc. Sample Cycle
Sent to Lab Lab Results Environmental Lab Sample Scanned and Sent to Relevant Laboratory Sample Preservation is key and must be done at the time of sampling!
Immediate analysis means 15 minutes!!! Do Your Research!!! Be Sure of the Analysis Needed! Are the Samples In Tact and In Proper Containers? Your sample must be received between 0 and 6 degrees Fahrenheit. Shipping Samples "Sample data is only as good as the sample taken." DO YOUR RESEARCH! Be Sure of the Analysis Needed Completed Paperwork Makes A Big Difference Receiving Department Cycle Resources Electronic Data Deliverables (EDD) Laboratory Analysis and Sample Documentation Sample Acceptance Is Not Always Up to the Client ELEMENT REPORT Interferences:
Residual Chlorine in Nitrite, Ammonia and BOD.
3.5 grams Na2S2O3/L. Use 2mL/mg Cl2/L.
Leaves, sticks, floating fat, bugs et al. For TSS.
Remove abnormal particles. Analytical Challenges Did the Sample Maintain Proper Temperature? Was the Sample Properly Preserved? Was the Holding Time Met for the Analysis Requested? Are the Samples Being Analyzed for Regulatory Purposes? Preservation Guidelines Difficult Matrices Compost Floating Particles Sludge Rocky Soil Sample Size Don't assume your lab can do what you see on T.V.
