    Hello Kathleen: IFFO, the Int. Fishmeal and Fish Oil Organization
    conducted a ring test during 2001 on the determination of histamine in
    fishmeal. Labs used the AOAC fluorometric method, HPLC or test kits. When
    I asked for comments from the participants on the protocol, no one remarked
    that histamine sticking to glassware was an issue. There were 2 kit
    manufacturers involved in this ring test and all of the laboratories were
    "expert" in this analysis in that they were internationally recognized and
    approved commercial labs. The only mention for HPLC is that the glassware
    must be thoroughly cleaned and suitable for HPLC analysis.

    Hope this helps.

    Regards

    Tony Bimbo
