Hi Mark,
<div class=""><br class="">
</div>
<div class="">I have used the brute force method and it is unpleasant. A field service engineer once told me he had heard you could freeze the gunked up parts in LN2 and then it would crack off but I have not tried that yet.</div>
<div class=""><br class="">
</div>
<div class="">I am curious what you use as a cold trap as I would like to do more to keep that stuff out of our dry pumps.</div>
<div class=""><br class="">
</div>
<div class="">Thank you,</div>

Greetings all -
<div class=""><br class="">
</div>
<div class="">is there a preferred procedure for cleaning sulfur deposits from a DRIE cold trap and unheated length of roughing line? i am reticent to apply a ‘brute-force’ method when a more elegant solution is available (and perhaps using the word ‘elegant’
regarding sulfur cleaning is mis-guided…) but even still, i am open to suggestions.</div>

<div class="">thank you so much</div>
