Method of detergent

Dear All,

Any one has a method of detergent available by HPLC?

Best Regards,

Rejane

Dear Rejane,

there is no universal analytical method for detergents. First you need to ask the supplier to disclose the composition of the detergent, both components and content of each in the formula. After setting the accepted residual level of detergent in the equipment you must identify the last to rinse component, to be used as tracer for the rest, and only then get (or develop) an analytical method for that component.

What about if multiple detergents are used in production in various departments?

Which detergent and/or excipient of a detergent would be used in this case?

What if the supplier refuses to disclose all excipient quantities or they only give a range e.g 5-15% caustic soda??

Thanks
