You are given a buffer that is labeled 10x and your instructor asks you to dilute it to 1x in the final tube.  If you have a final volume of 100uL in your tube how much of the 10x buffer will you need to add to bring it to 1x?  Do you need to add anything else to the tube before using the new solution?

What are the precipitates that were produced during the calcium and chloride ion test when it comes to Analysis of Blood? Write the equations involved clearly and easily understandable.

The Benzodiazepines test device is a qualitative, preliminary test which would be able to detect whether Benzodiazepines are present in the urine specimen at the cut-off concentration of 300 ng/mL. Is it possible to have a urine specimen which was interpreted as POSITIVE using the Benzodiazepines test device to be interpreted as NEGATIVE by Gas Chromatography/Mass Spectrometry? Justify your answer. A study was conducted by the manufacturer of the benzodiazepines test device to determine whether some compounds would have cross-reactivity at levels of 100µg/mL. List down examples of non cross-reacting compounds
