Microprobe Imaging

bio_imageOxford scientists pioneered the use of microprobe ion sources for radiocarbon AMS.  This method had sub-micron resolution, and could be used to image radiocarbon labelled material in tissue or other biological samples at higher sensitivity and resolution than autoradiogr

GC

Other area that they are working on is GC-AMS. With this method GC separation is used in conjunction with AMS measurement to detect the presence of radiocarbon in particular compounds. The method is highly sensitive with natural abundance radiocarbon measurable to a precision of about 10% for sample sizes of the order of 1ug.
