Established in 2000, Bay Instruments, LLC assists researchers in acquiring the membrane inlet mass spectrometry (MIMS) capability developed by Todd Kana and colleagues at Horn Point Laboratory of the University of Maryland. Our focus is rapid, high precision measurement of the dissolved air gases, nitrogen, oxygen and argon, for applications in aquatic denitrification and system metabolism. We also provide solutions for other applications. Bay Instruments sells complete systems and specialized inlets, and we provide application expertise and assistance.
Bay Instruments provides services and products in three core areas:
- Manufacturer of Membrane Inlet Mass Spectrometers for high precision dissolved gas measurements
- Distributor of WALZ photosynthesis equipment for the USA and Canada
- Reseller of Pfeiffer Vacuum mass spectrometers and vacuum equipment
Bay Instruments MIMS
Bay Instruments offers a unique MIMS that is optimized for the challenging requirements of environmental science. We currently have instruments in 14+ countries and numerous universities and research facilities throughout the United States. Our first installed instruments are still going strong. Our niche market for measurement of the dissolved air gases has been our emphasis and Bay Instruments remains close to the environmental science and oceanography communities.
The N2/Ar technique for denitrification is effectively synonymous with the Bay Instruments’ MIMS. However, we are always open to new applications that would benefit from our MIMS solution. We have worked with industry and government laboratories (see Applications) developing new capabilities and applications. We have a track record of working with end-users and subsidizing feasibility projects prior to purchase commitments. Sometimes it pans out, sometimes it doesn’t.
The Bay Instruments’ MIMS is the culmination of 20+ years of identifying, understanding, and optimizing the technique for high precision, high accuracy, and high reliability. We attempt to make quadrupole mass spectrometers look like high performance isotope ratio mass spectrometers from the data perspective. We often come close, and at a much lower price, (equipment and labor included). We have assisted others in retrofitting their non-optimal MIMS instruments with our membrane inlet configuration.
We believe in Keeping It Simple, which many of our clients appreciate. Nuances of the instrument and applications are many and our clients value our accumulated knowledge and expertise.
WALZ distributorship for the US and Canada
In 2015, Bay Instruments became the exclusive distributor of WALZ photosynthesis equipment for the US and Canada. Our founder’s academic research includes 20+ years of experience with WALZ chlorophyll fluorometers, both for research and teaching. We provide technical, marketing, sales and training assistance to the WALZ company. We keep a limited range of instruments at our facility for demonstrations and loans.
Pfeiffer Vacuum equipment reseller
We have incorporated Pfeiffer Vacuum quadrupole mass spectrometers and vacuum equipment in our MIMS since 1990. Pfeiffer Vacuum’s reputation for quality and reliability has translated to Bay Instruments MIMS that are low maintenance and high quality. Our relationship with Pfeiffer Vacuum allows us to quote equipment at substantial discounts in many cases. We sell only new, fully warrantied equipment. We are happy to provide quotes for any item in Pfeiffer Vacuum’s product line.
