In a world where explosive, toxic or otherwise lethal substances are, sadly, are becoming increasingly common in civilian areas, the ability to detect and identify hazardous chemicals and compounds quickly, easily and at significant range is highly attractive. Even after an attack has occurred, significant danger still exists from the threat of further concealed devices, thus significantly impeding the rendering of aid until the scene is declared safe. While there has been significant investment in sensor technology to address this need, no single solution has yet been demonstrated which can fulfil the often-conflicting needs of high sensitivity, speed, low cost, ease of use, portability and the ability to detect and identify multiple target molecular compounds against confused and unforgiving scenes.
CHEQUERS developed a device which addresses the urgent requirement for highly portable, low‐cost detection hardware. We optimised the usability and value of the instrument by sacrificing unnecessary (i.e. long‐range) performance. Therefore, for use in confined areas, or scenes where the presence of dangerous substances is suspected, we developed a very low‐cost, highly‐compact, handheld device, which, will be highly pervasive due to its lower cost, extreme portability and ease of use.
By working with potential end users of the devices and taking on-board their feedback at relevant stages throughout the duration of the project, the ultimate goal of the CHEQUERS project, to develop a highly impactful technology, which will deliver safety, security and economic benefit to society, has been achieved.
