Mass spectrometry (MS) is a valuable tool that can give you vast amounts of MS data to help you identify and quantify components. MS has been used to discover, determine, and quantify sample compounds in the proteomics, metabolomics, imaging, and glycomics applications across the food, pharmaceutical, and environmental industries. Combining MS with appropriate software and computer technology allows the possibility for more extensive applications. But first, we must understand the basics.

Data is to scientists as a saucepan is to chefs: essential. But with many analytical techniques, instruments, and software applications, extracting real insights from data can be challenging. Read more about how browser-based systems are revolutionizing analytical data processing.

Interpreting the pattern of lines on a mass spectrum may feel overwhelming at first glance. However, with a little background knowledge of the theory behind mass spectrometry techniques, you can begin to recognize what to look for in your mass spectrum and obtain the information you need. Read more about how ACD/Labs analytical data processing tools can help.

ACD/Labs is launching a new podcast! The Analytical Wavelength will cover industry trends and topics for scientists working with analytical data. Read on for more insights about data and the mass spectrometrist, and a link to listen to Episode 1.

There just doesn't seem to be enough hours in the day to get everything done. There are ways to gain time and be able to do more but they can be difficult to identify because until we’re exposed to them we carry on as we always have. If you are still doing any of the things discussed here, then there are ways you can gain hours in your day and even do your job better than you are right now!

The warning flag for this puzzle is evident in the intensities of the signals. For an unknown compound, the TOF-ESI+ mass spectrum below shows the expanded region around four isotope clusters at m/z 300.336 ([M+H]+), 322.307 ([M+Na]+), 599.672 ([2M+H]+) and 621.611 ([2M+Na]+). The intensities of the 13C isotopes (i.e. the [M+1] signal) vary between 40...

A key element in data interpretation is to identify any warning flags. Warning flags can help a chemist differentiate good data from bad data. For an unknown compound, the TOF-ESI+ mass spectrum below shows the expanded region around four isotope clusters at m/z 300.336 ([M+H]+), 322.307 ([M+Na]+), 599.672 ([2M+H]+) and 621.611 ([2M+Na]+). Are the intensities...

Many analytical data rely on common calculations. This puzzle covers one such common calculation. NMR and MS data were collected on two unknown compounds. The TOF-MS data shows the [M+H]+ at m/z 300.0000 and 600.000 at an error of 0.001 Da. The 500 MHz 1H NMR spectrum shows two chemical shifts at 1500.00 and 3000.00...
