BaySpec, Inc., founded in 1999 with 100% manufacturing in USA, is a vertically integrated spectral sensing company. BaySpec designs, manufactures, and markets spectral instruments, including a new class of OCI hyperspectral imagers, novel transportable mass spectrometers, UV-VIS-NIR-SWIR spectrometers, and OEM spectral engines and components, for precision agriculture, R&D, biomedical, pharmaceuticals, food safety, forensics, material science, and telecommunications industries. Using miniaturized linear ion trap technology, our instruments feature high sensitivity, light weight, and compact size. Equipped with two sample inlets for low pressure and atmospheric sampling. The Portability is lightweight and battery operated, while the Continuity allows continuous atmospheric pressure sampling with ppt detection limit. Specifically designed for field applications, these compact mass spectrometers are extremely easy to use and maintain, and ideal for a variety of bulk or trace detection.
