ASMS 2023 ThP051 Social Media for Mass Spectrometry
ASMS 2023 ThP051 Social Media for Mass Spectrometry


Social media for mass spectrometry dates back to periodic newsletters sent through the mail which were followed by electronic mailing lists, Usenet newgroups, and websites, leading to the platforms of today such as Facebook and Twitter. The goal of this presentation is to quantify the use of social media use in the field of mass spectrometry and by the American Society for Mass Spectrometry, explore the uses and utility of current social media platforms, and identify opportunities for improved communication in the field.


Through the latter part of the 20th century, scientific organizations distributed news of general interest through quarterly newsletters sent through postal services. The newsletter for the ASTM E-14 subcommittee and later the American Society for Mass Spectrometry was known as The Spectaker. As the Internet became more widely used in the 1990s, manually curated and automated mailing lists were used increasingly for the distribution of information. Usenet is a text-based distributed discussion that was widely used in the 1990s and was associated with Unix computer systems found at many universities. A Usenet newsgroup for mass spectrometry called sci.techniques.mass-spec was established in 1995 and operated until 2010. In the 21st century, information distribution and discussion has moved to the World Wide Web and, with the increasing use of smartphones and other mobile devices, have become ubiquitous in society and the sciences.

Social Media Platforms

Social media sites can be broadly classified based on the format of their content. For example, YouTube and TikTok focus on video whereas WhatsApp and WeChat on messaging. The popularity of a social media site can be quantified through the monthly active users (MAU) which is the number of unique users who visit the site each month. The table to the right gives the top ten most popular social media sites with the year they were started, primary content, and millions of MAU (Ortiz-Ospina,, 2019).

The top three discussion sites are Webio, Reddit, and Twitter, each with more than 300 million MAU. Of the three, Twitter is most widely used currently by the mass spectrometry community and is the main focus of this presentation.

Twitter Post Dataset

The dataset used for this presentation was obtained from the company TrackMyHashtag and comprises 80,036 Twitter posts and ancillary data made between 24 March 2009 and 31 December 2022 that contain the hashtag #MassSpec. This hashtag is the earliest and most widely used of those associated with mass spectrometry. The data was processed using Microsoft Excel to generate the plots shown in this presentation.

Twitter Statistics for #MassSpec

A dataset containing all Twitter posts using the hashtag #MassSpec from its first use in March 2009 through the end of 2022 was used to investigate the use of a social media platform by the mass spectrometry community.

Tweets with hashtag #MassSpec

The plot above shows tweets, retweets, and replies to tweets with the hash tag #MassSpec each year from 2009 โ€“ 2022. Rarely used before 2014, retweets now constitute half of all posts. Replies make up less than 2% of posts.

Influence of #MassSpec hashtag

The popularity of a hashtag can be quantified by reach and impressions. Reach is the number of users to whom the content is displayed whereas impressions is the the number of times content is delivered to a feed or timeline. Each #MassSpec tweet reaches about 1000 users on average.

Hashtags in Mass Spectrometry

The top fifteen hashtags occurring with #MassSpec are shown below for the complete dataset (left) and for 2022 only (right).

Hashtags occurring with #MassSpec

For the past ten years, the hashtag #ASMS[year] has been used for the yearly conference. For example, #ASMS2018 indicated the San Diego ASMS meeting and the 2023 meeting in Houston is represented by #ASMS2023. From 2015 to 2020 there were 100-200 tweets with the conference hashtag but this increased to more than 500 in 2022. There are around 50 tweets per year with the hashtag #ASMS.

Before 2012, there were fewer than 100 Twitter users using the hashtag #MassSpec and this number increased to greater than 1000 in 2017, more than 2000 in 2018, and more than 3000 in 2020.

Users per year

The number of tweets per user (above inset) has for the most part remained around 2-3 even as the number of users has increased. The exception was 2011-2013 when the number of tweets per user was more than 10.

Twitter posts are dominated by prolific posters (above). The top ten posters account for 40% of the tweets containing the #MassSpec hashtag. In 2022, only 15 users posted an average of more than one Twitter post per week.


A database of Twitter post โ€œtweetsโ€ was used as gauge of the utility of social media for the mass spectrometry community. Between 2009 and 2022, more than 80,000 tweets were posted with the hashtag #MassSpec as an indicator of their relevance to the topic. On average, each tweet reaches 1000 users and displayed 3000 times. Although nearly half of all tweets are retweets, the rate of replies is less than 2% indicating passive engagement. This is further evidenced by posting dominated by the most prolific users.

Social media is a valuable resource for mass spectrometry, but its utility can be improved through wider use and higher engagement. Potential routes to improvement include

  • Greater social media engagement by mass spectrometry societies and organizations through dedicated social media coordinators.
  • Coordination of employment and recruiting on social media.
  • Automated posting of mass spectrometry journal content using RSS syndication feeds.
  • Social media-based outreach for education.

Without a larger top-down coordinated effort, mass spectrometry on social media will likely remain largely passive and unlikely to achieve its full potential as a medium for information, education, and outreach.
