Indicate whether each is a characteristic of solid phase extraction (SPE) or solid phase microextraction (SPME). 1. Can be only used for liquid-phase samples 2. Uses a relatively smaller sample volume, (ex. 4 mL) 3. Requires a liquid-phase extraction step after desorption. 4. Uses a relatively large sample volume, (ex. 500 mL) 5. Uses a small fiber or tube coated with a sorbent material. 6. Can be used for both liquid-phase and gas-phase samples 7. Uses a solid adsorbent, such as silica or polymer beads, packed into a column. 8. Solvent-free extraction

Choose the one answer that fits best. Which of the following statements regarding the proper procedure for using Micropipettes is NOT correct? O a. You cannot use a 2-20 µl micropipette to pipet 200 µl O b. To expel all the liquid from the tip, you have to press the eject button O c. To draw up solution, press and hold the plunger at the first stop before entering the solution O d. Micropipettes always require the use of a disposable plastic tip O e. While pipetting, micropipettes should always be held as straight as possible
6) 1 mL of supernatant is required for a procedure. The final colored solution proves to be too high to read accurately on the spectrophotometer. 100 μL of supernatant and 900 μL of distilled water are substituted for the original supernatant and the procedure, run as before. The reading from the standard curve is 46 mg/dL. What is the actual amount of substance in the patient serum?

A nurse reconstituted a vial of 750 mg Cefuroxime Sodium Powder for Injection with 6mL of sterile water for injection. The reconstituted solution was dark amber-colored solution. The package insert states that solution colors range from clear to yellow depending on concentration, diluent, and storage conditions. The nurse was then hesitant to give the patient the solution due to its unusual dark color. Five portions were taken from a batch of cefuroxime sodium. Prior to testing in the instrument, each part was subjected to one of the following conditions: Conditions Specifications Temperature Portion 1: 8°C ± 2°C Portion 2: 30°C ± 2°C Portion 3: 40°C ± 2°C Light Portion 4: Kept in the dark Portion 5: Exposed to direct sunlight 1. Which form of the product – the powder for injection, the reconstituted product, or both – will you subject to the following conditions? Why do you think these forms can best address the problem?

After performing a plate and liquid lysate, it was found that the plate lysate achieved the common titre range of 1010-1011 pfu/ml whereas the liquid lysate achieved a range of 108 PFU/mL; what is the reason for the lower titre in different methodologies? How can we troubleshoot this issue in the future?
