In TLC or thin layer chromatography, RT  is the same for a particular compound if the chromatographic parameters are the same for every TLC procedure used to separate this compound.

You are analyzing glucose values using a spectrophotometric assay.  You noticed that the specimen is lipemic.  The analytical range of your instrument is 100-1000 g/dL. Your instrument gave an error code when it analyzed your patient sample. You decided to perform a 1/10 dilution of your sample.  And it gave you a result of 35 g/dL.  What result would you use to report to the physician?

The images below represent the results of normal (left image) and abnormal (right image) levels of control that are tested daily for a specific analyte. On which day should the run be rejected if Westgard rules are used to evaluate QC? Questions: a. On which day and which control level should the run be rejected, if any? (2pts) b. If there is a QC violation, what specific QC violation was observed? (1pt) c. What type of error, if any, would this represent? (1pt) d. State at least one source that contributed to this type of error. (1 pt) e. State at least one way that you would troubleshoot this error. Be concise and specific for full credit. (1 pt)
