All pulled ESI emitters are made of quartz silica. For optimum performance, the inner surface is rinsed with acidified water, but you will need to condition it for your set-up. This will happen automatically in the first two runs of your nLC workflow. When you install a new emitter, we recommend you to pass two standard runs before analyzing your samples.
Fresh Bioscience Ltd. offers two types of integrated emitter fused silica capillary tubing, fritted and non-fritted. All tubing are designed for user to self pack their own nanoLC columns with high performance and reproducibility. Normally we recommend fritted ♕integrated emitter fused silica capillary tubing for peptides mapping, it drives the highest proteomics performance available. A consistent results over multiple experiments and hundreds of injections, which always make you be happy.
