WELCOME Protocol Analytical Customers!

For the past three years SPEX CertiPrep and Protocol Analytical have been working side by side to create one company to provide you with all of your Inorganic and Organic Certified Reference Materials. Protocol Analytical will continue to manufacture your organic standards while SPEX CertiPrep will handle entering your order, shipping your order, invoicing your order and handling any customer service issues you may have. You have a sales person who is available to work with you on custom requests and technical support. If you would like to know who your rep is, please email us.
