This month we have a HOT article from our Analyst Editorial Board member, Graham Cooks. Working with his colleagues from Purdue University, USA, they have developed a rapid, point-of-care method to test whole blood samples that have been supported on filter paper using paper spray mass spectrometry. Addition of a coagulant called alum allowed the sample to be tested right away. The technique was tested on the analysis of therapeutic drugs in blood samples. Click through here to read more. The paper will be free to access for 2 weeks!
