<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Century Schoolbook","serif";color:#1F497D">It is my understanding that the arsenic was in a paste form applied to the inside skin of the animal. It is tiny crystals of this that can migrate to
the surface when dry. If the “cotton swabbing” method is being used, it seems that it depends on whether or not you happen to capture a crystal on your swab. I’ve always been slightly skeptical myself as far as whether my “negatives” are valid. Anyone else
have this problem?<o:p></o:p></span></p>

<p class="MsoNormal">So we have done some fairly extensive testing in our collection and had the same results. Generally this happened where arsenic prepared specimens were in contact with "clean" specimens" and from the literature I am understand that there
can be cross contamination. So if possible, you want to quarantine your arsenic specimens away from clean specimens if possible (there are a number of ways to accomplish this).<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Recently I attempted testing for arsenic in the mounted specimens of our collection. 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>
