Sorry you are having issues. What kind of nebulizer are you using? The old style with lock nut, a torx/set screw or one with hex set screw. Are you using the video from the 6100 Resource DVD?
Answers to your questions:
1.There is a little wire inside the needle that needs to be removed after putting through ferrule.
2. Once you get the ferrule on, slide needle through needle holder, push the needle into the ferrule until the needle is slightly visible, flush with the end of ferrule. Reinstall locknut and union, hand tighten the union onto the guide and ferrule. using a wrench hold needle holder steady. Turn union 1/2 to 3/4 turn. You should not have to go more than this. You should hear a little squeak when ferrule is compressed. Bring lock down onto the union. Check the needle by gently pulling on it.
3.We don't have schematics, but curious which video you are using and which alignment jig?
Let me know,
Thank you for your responses. I am using the old style with lock nut. The video is one that the tech copied to the desktop when he installed the equipment originally (back in 2007). I have since seen a new one when I called tech support for help. Your answer with response to the needle makes sense; I wasn't sure why there was a thin wire (I mistakenly thought that was the needle) because it's not mentioned in the directions. The new needle flange that they sent has a different design then the original; it already has a nut that is fused to the part and so it's not like the original which had a nut that screwed on (below the union). I am not using an alignment jig (although I do have a stainless steel block to hold the ESI needle when I removed it from the interface), is this something that is critical to use and what is the part number? I can see the tip of the needle because I am using a microscope to view it, so is it necessary or just convenient?
