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.
