Labs for L-Lysine Content Testing in Feed Grade Additives

Hello all,

I have been looking to verify a manufacturers product by testing for the parameters on their COA, but am having difficulty finding a lab in the United States that is able to perform said testing. 

The product is L-Lysine HCL, monohydrochloride, Feed Grade - Additive. 

I am looking to have the product tested for the following:

- L-Lysine HCL Content (Minimum 95%),

- L-Lysine Content - (Minimum 78%)

We require additional testing, such as moisture, heavy metals etc. but I have sourced that.

My hopes are that someone within this form has experience or knows of a lab capable testing for the L-isomer specifically. So far, I've only had labs able to test for total Lysine content. 

Thank-you for any help you may be able to provide me. 

Regards,

Gareth.
