THE results of an investigation of the application of paper chromatography to the identification of the common barbiturates were recently reported by this laboratory. 1 If a barbiturate is found ...

Abstract: This paper details the design, fabrication, and characterization of a novel disposable MEMS airflow sensor, employing Bare Conductive electric paint deposited on Whatman 3MM chromatography ...

It works by combining the best properties of paper and plastic materials to create a hybrid testing surface that can detect multiple cancer markers simultaneously. The system uses ordinary ...

This activity is a fun introduction to chromatography while learning about the different planets in our solar system. The idea is that children create each planet using filter paper while thinking ...

This article provides a general overview of untargeted analysis using comprehensive two-dimensional gas chromatography (GC×GC), while revisiting some fundamental aspects of method development. The ...

Lipidomic studies are often conducted using shotgun mass spectrometry (MS) or reversed-phase liquid chromatography coupled with MS (LC–MS). However, chromatographic separation offers several ...

The team used a cellulose chromatography paper with a serpentine design to serve as an effective microfluidic channel transporting excreted sweat through the porous medium without external force ...

This simple felt tip pen paper chromatography experiment is a great way to learn about this particular method of separating mixtures. Felt tip pen chromatography is a fantastic science activity for ...

This white paper discusses how two-dimensional liquid chromatography (2D-LC) provides a superior solution for the analysis of complex samples owing to its improvement in both separation selectivity ...
