We have entered a new stage in the era of accelerations. Moore’s law continues its expansion, increasing exponentially the computer power available. Other accelerations are remarkable, particularly easy access to cloud computing and the expansion and influence of artificial intelligence to practically all sectors of our society.

This article describes the development of a new data-independent acquisition (DIA) workflow for protein quantification that uses a mass spectrometer that combines three types of mass analyzers to achieve lower limits of detection (LOD), higher sensitivity, more accurate quantitative results, wider dynamic range, and better reproducibility than existing high-resolution accurate-mass (HRAM) tandem mass spectrometry (MS-MS) DIA workflows.

Data Handling/Software

Chromatographers rely on software for many laboratory functions, including method development, instrument control, data acquisition and analysis, and data archival. Participants in this Tech Forum are Tony Owen of Agilent Technologies, Damien Rosser of ALMSCO International, David Chiang of Sage-N Research, and Mark Harnois of Waters Corporation.

Software traditionally used to control and process data in analytical instruments is now being expanded to include functions such as automated system monitoring with maintenance feedback alerts and interactive diagnostic routines that enable users to quickly track and resolve the source of many system problems. As a back up to these functions, a second layer of expert support is being made available by some instrument vendors to address more complex servicing issues. For larger or more elaborate instrument installations, monitoring and diagnostic software functions can be integrated with remote servicing expertise in a networked configuration to provide continuous proactive instrument maintenance. The benefits of these innovations include lower and more predictable operating costs, reduced system downtime, and more efficient utilization of the instrument user's time.

This column discusses potential sources and ways to avoid out-of-specification (OOS) results and highlights the draft FDA guidelines on OOS investigations.

The November 2001 installment addressed requirements and potential problems associated with the acquisition of fast chromatography peaks at detectors and data-recording systems. Hinshaw continues the topic in this month's column and treats issues that involve qualitative data reduction after a chromatogram has been acquired.

This "Data File" column shows readers how to incorporate e-mail in chromatography data systems and suggests how other Internet technologies can improve modern laboratory practices.
