Recently, I got two invitations to become an editor for two journals (at the same day). At first I was very surprised and willing to accept the offer.

From a for atto to z for zepto
Todays detection limits are very low. Using various methods such as amperometric detection [1], surface plasmon resonance [2], and laser–induced fluorescence detection [3] it is possible to sense few attomolar (10-18 mol·L-1) concentrations of analytes.

ICP-OES: Why spectral lines are true peaks and how this can fool the user.
ICP–OES is a common technique in analytical chemistry, which is characterized by simplicity, simultaneous multi-elemental determination capability, high sensitivity, linear dynamic range, low detection limits, and good precision [1]. It seems to be the perfect method for element analysis (esp. metals). However, sometimes it can fool the user.
