Preparing Samples
• Isolate and purify samples before measuring them with the instrument. Commercial
sample isolation kits are available for these purposes, or use an in-house protocol. After
purification, analyte of interest is typically dissolved in aqueous buffer solution before it is
measured.
Tip
: Any molecule that absorbs light at analysis wavelength will contribute to total
absorbance value used to calculate sample concentration.
• Ensure final analyte concentration is within instrument’s
.
• For micro-volume measurements, gently (but thoroughly) vortex each sample before
taking a measurement.
Avoid introducing bubbles when mixing and pipetting. For more information, watch

5. Measure a sample:
–
Fill clean cuvette to same height with sample
solution
–
Replace blanking cuvette with sample
cuvette, making sure to align light paths
–
Tap
Measure
–
Wait for measurement to complete
–
Remove cuvette
–
Clean cuvette according to manufacturer
specifications
Note
Samples dissolved in extremely volatile solvent such as hexane may work best with
