Alternate methods for 1100 seal wear in procedure

Question

I have replaced the pump seals and secondary seals on the binary pumps of our 1100. I don't have the restriction capillary and adaptor to connect the solvent bottle directly to the pump inlet. Can I still do a seal wear in? Is it ok to go through the solvent degasser and selection during the procedure? Any alternatives for the restriction capillary?

Hi tnaka, theoretically it should be fine going through the degasser (since you will be using IPA for the seal wear-in process). Although we still recommend that you purchase both the adapter and the restriction capillary from our website so that the wear-in process can be done as designed. The restriction capillary is used to generate backpressure in the system. You should refrain from running your system without either a column or restriction capillary attached as this could damage your detector (especially if you have a fluorescence or refractive index detector).
