FAQs
Is LR grade suitable for titration standards?
No. Standards and volumetric solutions should be prepared from AR, ACS or primary-standard grade reagents with defined assay and impurity limits.
What does SQ or synthesis grade mean?
These are manufacturer names for grades broadly similar to LR: adequate purity for synthesis, without full analytical impurity limits.
Is LR grade the same as technical grade?
No. LR is purer and more consistently specified. Technical grade is intended for industrial processes and may have few or no impurity limits.
