using DA reprocessor and custom workflow builder for automating acquisitions (importing formulae from a worklist)

How to confirm identification of molecular features using MS/MS. See video Ep05 in the series for creating MS/MS inclusion list.

Using Molecular Feature Extraction (MFE) - estimating background noise, formula prediction using molecular formula generation (MFG). Using databases to assign IDs and exporting for MS/MS

Manual reviewing and automated workflow of RNA Oligonucleotide UV data, verifying delay times and determining the purity of the peak using different approaches. Includes some tips on integration algorithms.

how to extract Base peak chromatograms (BPCs), Extract ion chromatograms (EICs), instrument curves from data files.

Extracting spectra, different ways of creating extracted ion chromatograms (EICs), subtracting background spectra, using the Mass caliper, Mass isotope calculator. Basic EIC extraction from MS/MS data files, basic fragment interpretation.

Qualitative Analysis - Ep01 - Navigation Part 1. Basic navigation, opening files, zooming, layouts, basic subtracting of spectra.

Informative video on how to start fabricating a camera mount adapter that will repurpose existing action camera accessories. An M6 bolt is used instead of ¼” screw, as this was readily available. We delve into the Onshape part design and Cura slicing. See the link for the basic design in Onshape: cad.onshape.com/documents/1050dbd8a0cf5437b7817899/w/f9da46b6c147699889c8469b/e/72558fab94499ff4b72...

A subsequent follow-on discussion of confirming MS/MS or fragmentation of diazepam in High Resolution Mass Spectrometry (HRMS).

Brief evaluation of LC-MS high resolution mass spectrometry (HRMS) data with discussions around mass accuracy (or error) and what we can infer from isotopologues.

This video outlines the procedure to utilise Personal Compound Databases and Libraries (PCDL) to screen for compounds in a sample. The data was acquired using a Agilent 6545 QTOF in All Ions mode using normal phase chromatography on a HILIC-Z column.
