ON-GOING STABILITY STUDIES

Chem Service is committed to providing our customers with high quality analytical materials. As part of our quality program, our
Standards Grade materials have on-going, lot-specific testing. The testing program for all Standards Grade materials will certify the
standard for purity, identity, concentration, and stability. Subsequently, through on-going testing, our Standards Grade material is tested
to ensure it has maintained the certified quality. If we detect a purity or stability problem during the on-going testing, which will affect
the expiration date of a Standards Grade material, rest assured, we will alert our customers and offer a replacement.
