Our wet lab is equipped with an Atomic Absorption Spectroscopy machine for complete analytical control of all process solutions. This analysis provides us with superior process control to maximize the consistency and quality of our products. The wet lab processes regularly scheduled chemical sampling and includes a complete chemical sampling laboratory to maintain and monitor chemical bath composition. We use select off-site chemical laboratories to supplement our in-house chemical testing to ensure a high level of process control in our operations.
