Tuberculosis Diagnosis Using GCxGC–TOF-MS

The Column spoke to Jane Hill from Dartmouth College, USA, about her group’s development of a breath analysis method for tuberculosis (TB) diagnosis using multidimensional gas chromatography–time-of-flight mass spectrometry (GCxGC–TOF-MS). read more

Improve Vaporized H₂O₂ Bio-decontamination

Learn how inline measurement of vaporized hydrogen peroxide can help reduce the number of indicators required for validation. Continuous measurement that includes values for several parameters – H₂O₂ concentration, temperature, pressure, relative humidity – helps you control and assess process performance. Condensation can be accurately predicted using the Relative Saturation parameter – crucial to successful bio-decontamination. Read this blog
