1. A mobile chemical sensor device comprising:
a housing including a cartridge opening;
a cartridge configured to position at least one chemical sensor probe having a sensor-bearing surface that includes an array of luminescent chemical sensors, wherein the cartridge forms a light sealed enclosure in an interior of the housing when the cartridge is inserted in the cartridge opening;
at least one light source configured to direct light onto the sensor-bearing surface of the at least one chemical sensor probe at an angle of incidence, wherein the light source is capable of emitting light having a wavelength of from about 280 nm to about 400 nm; and
a camera module mounted in the light sealed enclosure and configured to detect emitted light from the at least one chemical sensor probe,
wherein the cartridge is configured to display an area of the sensor-bearing surface having a display length of about 15 mm to about 50 mm and a display width of from about 1 mm to about 20 mm, and
wherein the at least one chemical sensor probe has a probe thickness of from about 0.1 mm to about 2 mm, a probe length of from about 20 mm to about 60 mm, and a probe width of from about 2 mm to about 30 mm, or
wherein at least one of the housing and the light sealed enclosure include a gas intake and a gas exhaust, and wherein the gas intake and the gas exhaust are configured to allow a sample gas to flow across the sensor-bearing surface of the at least one chemical sensor probe.
