Letter from the Editor
Abstract
Dear Readers: Another year! The Journal is fast approaching its 40th year of existence and there have been quite a few “changes” in those four decades, both in chemical measurement science and in chemistry as a whole. I invite you to visit www.informaworld.com/batc , which is the website for Critical Reviews in Analytical Chemistry and, if you have a bit of spare time, examine the titles of the first year's articles. I can recall that the first issue was not that long after very good departments were still advertising that they had a single gas chromatograph for general use in support of research! Next year is the 50th anniversary of the Nobel Prize for the discovery of polarography and there is a chance we will devote an issue to that event. It is four decades ago that Prof. Perone at Purdue University reported the first use of a computer to both take data and control an experiment in the time base of the computer itself - another form of dynamic electrochemistry. Times change and timescales change as do the size of the objects of study. The Journal would be delighted to consider reviews on the analytical challenges posed
