Version 4.1 Release

Advion has just released a new version of Mass Express and Data Express – Version 4.1.

Advion has just released version 4.1 of its Mass Express software suite including updates to Mass Express, Data Express, Quant Express, and the much-anticipated Peak Express software for a robust package offering chemists the expertise of a dedicated mass spectroscopist, digging deep in to the data to find small, unknown peaks, as well as the ability to easily obtain quantitative LC/MS data.

The new Peak Express software featuring ΔS offers an ultra-sensitive technique that is able to detect even the smallest peaks amongst much larger signals from contaminants and chemical noise. It detects change, not absolute intensity, and zooms in on tiny rapid movements in a field of much larger static or slow-moving signals.

Quant Express, an addition to Advion’s user friendly Mass Expres 4.0 software suite, is a full feature quantitation application for LC/MS data. The quantitation method can be configured in Mass Express before the analysis or in Quant Express post-analysis and it supports calibration curves, internal standards, QCs and unknowns using SIM or scan mode data. An enhanced peak detection algorithm ensures highest accuracy and ease of use.

Features implemented and improved in Mass Express:

  • Control of gradient/binary pump
  • Flow chemistry support
  • Support staggered heating: prevent source gas and transfer line heaters from turning on before capillary heater is equilibrated
  • Features implemented and improved in Data Express
  • Multiple charge deconvolution; automatic and manual
  • Improvements to CheMS

To see what version you are running, click on the ‘i’ button in the System page in Mass Express.

If you wish to upgrade to the new software please contact info@advion.com for upgrade instructions.

iASAP Analysis of Air-Sensitive Compounds via Inert Sampling Techniques

Many chemical reactions carried out by synthetic chemists involve air-sensitive compounds such as metal catalysts and organometallics and must therefore be carried out in a glove box or using a Schlenk line to prevent oxidation and hydrolysis. Sampling and transportation of these samples to a mass spectrometer by an Atmospheric Solids Analysis Probe (ASAP ®)…

Identification of a Pesticide Used in Lawn Care by vAPCI Compact Mass Spectrometry

At regular intervals throughout the year a local lawn service applies pesticides to the lawn surrounding the Advion headquarters in Ithaca, NY. The grass is very uniform and not a single dandelion or crabgrass plant is visible – so we wondered, what chemical do they use? After an application in the early spring, we sampled…

Analyses of Different Grades of Olive Oil by Volatile Mass Spectrometry

In this application note, we demonstrate the use of the Advion expression CMS with a volatile APCI (vAPCI) ion source to analyze extra-virgin, virgin, and lampante olive oil samples. We show statistical analysis allowing us to categorize and identify olive oil samples by their grade. This technique allows us to test individual olive oil samples and…

Classifying Cheeses by vAPCI Compact Mass Spectrometry

Cheese is one of the world’s most popular food types, with a wide variety available for consumers. The scents and flavors of cheeses, so characteristic to each type of cheese, stem from a complex mixture of chemicals, including free fatty acids. While this mixture is affected by a wide variety of factors we can use…
