- With automatic settings
- When measured sample is potassium hydrogen phthalate solution and operations to prepare for the next measurement are performed.
- Please contact your local Shimadzu representative to verify the appropriate USB memory.
- If TN option is installed, oxygen and high-purity nitorogen cannot be used.
