No matter how sophisticated a fluid analyzer system may be, it will be ineffective if a sample flow fails to reach the analyzer sensor or if the sample is contaminated or stale.
An analysis of the two failed coatings applied previously showed that a high permeance of the coatings and the presence of pinholes in the coating were the primary cause of the failures. Both were approximately 65 percent solids by volume bisphenol A epoxies that had been applied in three coats to a total film thickness of 15 to 16 mils.
Whereas conventional synthesis of ionic liquids remains time consuming, microwave-mediated processes prove beneficial for these compounds. Immediate temperature control with immersing sensors prevents excessive overshooting of the target temperatures.
