Elemental pub quiz challenge

We would like to invite you to participate in the Analytical Challenge, a series of puzzles to entertain and challenge our readers. This special feature of “Analytical and Bioanalytical Chemistry” (ABC) has established itself as a truly unique quiz series, with a new scientific puzzle published every three months. Readers can access the complete collection of published problems with their solutions on the ABC homepage at http://www.springer.com/abc. Test your knowledge and tease your wits in diverse areas of analytical and bioanalytical chemistry by viewing this collection. The present challenge is dedicated to the periodic table, which celebrates its 150th anniversary this year. The United Nations proclaimed 2019 as the “International Year of the Periodic Table of Chemical Elements” and therefore, on this special occasion, there is more than one prize to be won (Springer book vouchers of your choice up to a value of €100).
