The barrel of the syringe is constructed of glass and is therefore susceptible to breaks and cracks. Over tightening the syringe can cause the syringe barrel to separate from the metal fitting that goes into the 8-port valve. <div class="ts-question">Is the syringe barrel cracked or broken?</div> <div class="buttons"> <span class="btn-yes">[[Yes->Syringe Replacement - WP (2768)]]</span> <span class="btn-no">[[No->8-Port Valve Leaks (3604)]]</span><span class="btn-back"><<back "Back">></span> </div></div>

If leaks appear here, the syringe may not be fully inserted. DO NOT over tighten. Verify that all of the tubes connected to the 8-port valve are finger tight and leak free. Replace the tubing to the 8-port valve as necessary. <div class="ts-question">Is liquid leaking from the bottom of the 8-port valve?</div> <div class="buttons"> <span class="btn-yes">[[Yes->Syringe Replacement - WP (2768)]]</span> <span class="btn-no">[[No->Halogen Scrubber Discoloration (3606)]]</span><span class="btn-back"><<back "Back">></span> </div></div>

The absorbent inside the halogen scrubber turns black as it absorbs chlorine. This discoloration band advances toward the outlet as the amount of chlorine absorbed increases. The halogen scrubber should be replaced when the discoloration band reaches the point shown in the diagram. <div class="ts-question">Has the discoloration band reached a point where it should be replaced?</div> <div class="buttons"> <span class="btn-yes">[[Yes->Halogen Scrubber Replacement - WP (2745)]]</span> <span class="btn-no">[[No->Membrane Filter (3608)]]</span><span class="btn-back"><<back "Back">></span> </div></div>

Click 'No' to transfer to the Decontamination procedure. These contaminants may leach into the carrier gas and cause an unstable baseline. These contaminants may also have an absorbent affect on the sample and cause reproducibility problems.
