Bacterial Metabolomics: Sample Preparation Methods by Khairunnisa Mohd Kamal, Mohd Hafidz Mahamad Maifiah, Nusaibah Abdul Rahim, Yumi Zuhanis Has-Yun Hashim, Muhamad Shirwan Abdullah Sani, Kamalrul Azlan Azizan

“…Nevertheless, the bottleneck in metabolomics has been the sample or metabolite preparation method. A custom-made method and design for a particular species or strain of bacteria might be necessary as most studies generally refer to other bacteria or even yeast and fungi that may lead to unreliable analysis. …”

Effect of Sample Preparation and Chromatographic Conditions on Background Signal by V. M. Kosman, M. V. Karlina, O. N. Pozharitskaya

“…The main limitation is associated with a significant background effect of biological matrixes, limiting the sensitivity of HPLC-UV methods.The aim of the study was to evaluate sample preparation and chromatographic conditions in terms of background signal level during HPLC-UV analysis of blood plasma.Material and methods: three types of blood plasma (rat, rabbit and human), three chromatographic modes, and three detection wavelengths were used to assess the effect of the precipitation agent, centrifuge conditions, and the inclusion of the solid-phase extraction (SPE) step into the sample preparation procedure on the background signal level during HPLC-UV analysis.Results. …”

Greenness assessment of 174 CEN, ISO, and pharmacopoeia standard methods and their sub-methods used for environmental, food, trace element and pharmaceutical analyses by Juan L. Benedé, Cecilia Cagliero, Emirhan Nemutlu, Francisco Pena-Pereira, Carlo Bicchi, Enrique Javier Carrasco-Correa, Maria Celeiro, Alberto Chisvert, Alessandra Gentili, A. Ruth Godfrey, Mehmet Gumustas, Fragoulis Krokos, Paramee Kumkrong, Maria Llompart, Marcello Locatelli, Zoltan Mester, Sibel A. Ozkan, Stig Pedersen-Bjergaard, Marcela A. Segundo, Marek Tobiszewski, Elefteria Psillakis

“…The widely adopted AGREEprep metric was applied to assess the greenness of the standard methods. The discussion begins with the overall scores of each method, followed by a detailed analysis of individual criteria, that highlights the strengths and weaknesses of the evaluated sample preparation methods in terms of greenness.The results revealed a generally poor greenness performance, as 67 % of the methods scored below 0.2 on the AGREEprep scale, where 1 represents the highest possible score. …”
