<p class="jove_content">In this protocol, we detail the use of polyacrylamide zirconium hydroxide hydrogels (ZrOH hydrogels) as a non-destructive, in-situ method for sampling root-exuded carboxylates from intact soil-grown roots at different crop developmental stages. It also outlines subsequent localized mapping and quantification of these carboxylates using Ion Chromatography-Mass Spectrometry (IC-MS).</p>

Polyacrylamide ZrOH Hydrogels for Spatially Resolved Sampling of Carboxylates Exuded from Roots Growing in Soil

Sampling and reliable quantification of root exudates from undisturbed soil-grown plant roots remain challenging. We further developed a non-destructive ...

<p class='jove_content'>Proton Transfer Reaction Time of Flight Mass Spectrometry allows high-sensitivity, rapid and non-invasive analysis of volatile organic compounds. To demonstrate its potential, we give three examples: lactic acid fermentation of yogurt (on-line bioprocess monitoring), different apple genotypes (large-scale screening), and retronasal space after drinking coffee (nosespace analysis).</p>
