How to Use This Tool
Step 01
Select Optical Path Length
The distance light travels through your sample. Standard spectrophotometry uses 10 mm. Choose shorter paths for concentrated samples, longer paths for trace-level detection.
Step 02
Choose Sample Volume
Semi-micro cuvettes hold 350–1750 µL in a narrower inner chamber. Standard cuvettes accommodate 1.5–3.5 mL. Micro cuvettes (≤100 µL) are available in Standard 80 construction.
Step 03
Set Wavelength Range
Determines the required quartz grade. JGS1 (170–2500 nm) is needed for UV and deep-UV work. JGS3 (260–3500 nm) covers NIR and IR applications. MQ does not stock JGS2.
Step 04
Pick Application Environment
Organic solvents, strong acids, or high temperatures require Sintered 80 or Molded 83 construction. Routine aqueous measurements are fine with Standard 80.
