Sample Injection Issue

• There are several causes for the needle breaking or bending.
• First, ensure the correct needle is being used.
• A 23 gauge syringe must be used with the AOC-5000 auto-sampler.
• Next, verify the red needle guide is in place on top of the injector port.
• See Figure 1 in the attached document titled, "Troubleshooting Needle Issues" to assist.
• Lastly,conduct a rail check on the auto-sampler to ensure it is properly aligned.
• Refer to the document titled “Auto-Sampler Needle Change” for guidance on aligning the auto-sampler.
