Advances in the analysis of steroid hormone drugs in pharmaceuticals and environmental samples (2004–2010)

High performance ion mobility spectrometry as a fast and low cost green analytical technology part I: analysis of nutritional supplements

“…Other than leucine, all of the other supplements have been previously analyzed using chromatography with a variety of detection methods from ultraviolet (UV) absorption to MS n [20,22,38,42,[44][45][46][47]57]. Electrophoresis methods have also been used more recently as well for the flavanoids such as EGCG [27,57].…”

Environmental aspects of using gas chromatography for determination of pharmaceutical residues in samples characterized by different composition of the matrix

“…It is observed that in the previous years most of the analytical protocols had been based on LC-MS (Kim and Carlson 2005, Ternes 2001, Petrović et al 2005, Görög 2011, Primel et al 2012, Tadeo et al 2012) (Chunhui et al 2016). However, during the last years many analytical protocols based on GC/MS techniques were developed and applied around the world for residuals analyses in environmental samples , Naing Li & Lee 2015, Omar et al 2016, Puckowski et al 2016, Afonso-Olivares et al 2016.…”

“…For example, these two techniques enable determining pharmaceutical residues in different matrices including biological, cosmetics, food and environmental samples (e.g. Petrović et al 2005, Görög 2011, Primel et al 2012, Tadeo et al 2012, Núñez et al 2012, Mohamed 2015, Puckowski et al 2016, Afonso-Olivares et al 2016. They are usually used for monitoring studies, routine analysis, stability studies and quality control.…”

“…The lower cost of GC analysis and the smaller amounts of solvent consumed also favour such approach. It was also reported that the limits of pharmaceuticals' detection are often smaller when GC was used, compared to the LC technique (Kot-Wasik et al 2007, Görög 2011, Shaaban and Górecki 2015. Moreover, the widespread availability of the relevant instruments in laboratories means that GC is an excellent tool for identifying and quantifying pharmaceuticals in different matrices which can be implemented in routine analysis in environmental, clinical and food analysis laboratories much more quickly.…”

Electrochemical Sensors in Environmental Analysis

“…These methods are still considered as nonselective and non-stable indicating methods. 54 Few studies used mercury as dropping 55 or hanging 56 electrodes. The voltammetric determination of finasteride in tablets and the assay of danazol in capsules by square-wave adsorptive stripping voltammetry were already reported.…”
