DBS is part of a wider term defined as dried matrix spot (DMS). Basically, the filter paper card can act as a carrier for any matrix enabling fully automated extraction and analysis from a dried probe. CAMAG currently focuses on LC-MS applications, however a huge variety of different methods, such as genetic procedures, biological assays or ICP-MS applications, have been published and may be accessible as well. The possibilities in this field are vast. New and creative analytical workflows can be established. One example is the automated analysis concept of Gutter oil from filter paper cards. Gutter oil describes illicit cooking oil which has been recycled from discarded used oil. The filter paper is a perfect sample collector and sample carrier to monitor the quality of cooking oil in restaurants.
