  1. Observations and Conclusion When acetic acid was added to the distilled water, the solution became acidic because because the concentration of hydrogen ions became greater than the concentration of hydroxide ions. Notably, this separation method is advantageous in its ability to concentrate large quantities of samples while simultaneously removing common interfering agents or unwanted analytes.
  2. Additionally, the use of microfluidic devices such as cIEF combined with online trypsin digestion, followed by analysis via nano reverse-phase LC-MS analysis [ 84 ], has proven to be advantageous in that few samples are needed, and it allows for the high-throughput analysis of low abundance proteins while reducing direct sample handling. Challenges arise after the separation, with regard to detection, as discussed later [ 26 ].
  3.
