My issues, that I hope some of you can help with, is that I am getting a negative result on specimens that I am sure have arsenic. Has anyone else run into this problem? If so how did you solve it? I am following the protocol developed by NPS in their Conserve-o-Gram 2/3 and using Hach’s arsenic test kit, since the one recommended by NPS is no longer made. Any suggestions would be most welcome. Feel free to contact me off list if you would prefer.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Lena Hernandez<o:p></o:p></p><p class=MsoNormal>Collections Manager/Registrar<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Museum of Science and History<o:p></o:p></p><p class=MsoNormal>1025 Museum Circle<o:p></o:p></p><p class=MsoNormal>Jacksonville, FL 32207<o:p></o:p></p><p class=MsoNormal>(904)396-6674 x212<o:p></o:p></p><p class=MsoNormal>lhernandez@themosh.org<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
