“…Malinina and co‐workers developed a method for the determination of several amines in drinking and natural waters by CZE with online ITP preconcentration. A BGE based on acridine as an absorbing ion (BGE = TE: 2 mM acridine, 20 mM HAc, 0.05% Twin 20, pH 3.3; LE: Na + from the sample) was proposed for analysis with indirect photometric detection at 254 nm.…”

This review brings a survey of studies on analytical ITP published since 2016 until the first quarter of 2018 and includes chapters about theory and principles, instrumentation and techniques, and analytical applications of ITP. It shows the position of analytical ITP among contemporary separation techniques, where particularly its unique concentrating capabilities keep the interest to include it into novel high-sensitivity analytical procedures. The reviewed papers are considered according to their nature, techniques used, and instrumentation employed. The significance of electrolyte system composition is emphasized by providing explicit values where possible.

“…Many of the recently reported GC methods provides a feasible method for detecting alkanolamines using specific columns that allow direct aqueous injections [5]. The CE [6,7] and IEC [8] methods were also used for determination of alkyl-and alkanolamines in drinking and natural waters samples, but alkanolamines have only weak UV absorbance, leading to a low sensitivity. The high-performance liquid chromatography (HPLC) coupled with post-column fluorescence derivatization (FLD) [9,10] require complex sample derivatization preparation and is time consuming.…”

Triethanolamine (TEA), triisopropanolamine (TIPA), diethanol isopropanolamine (DEIPA) are necessary cement additives, and knowing their contents is needed for quality control and also to understand final properties of the cement. Whether it is the production of grinding aids, technical research and development or application research all involve the detection of grinding aids. This work developed a simple analytical technique for the simultaneous analysis of these alkanolamines in liquid cement grinding aids using high-performance liquid chromatography (HPLC) combined with evaporative light scattering detection (ELSD). HPLC was conducted by an XBridge C18 column (with dimensions 4.6 × 250 mm and 5 µm particles) using methanol and 0.1% trichloroacetic acid as mobile elution phases. The ELSD sprayer and drift tube temperatures were 60 ºC and 90 ºC, respectively. HPLC-ELSD developed in this work demonstrated 1) high sensitivity with limits of detection for the three analytes are 0.15, 0.54, 1.04 µg/mL; 2) good linearity with correlation coefficients equal to 0.997-0.999 over the tested concentration range; 3) excellent repeatability with intraand inter-day CV below 2.71% and 4) satisfactory accuracy with recovery in the 95.5-100.8% range. This novel method is a powerful, time-and cost-effective tool for alkanolamine analyses and quality control.
