Company Information

Presentation

Sociedad Europea de Análisis Diferencial de Movilidad SL (SEADM) is a Spanish SME founded in February 2005 with the aim of developing a new generation of analytical instruments able to detect trace elements at the subfemtogram level, both in the atmosphere or within the body fluids, based on the know-how of its technical consultant and co-founder Juan Fernandez de la Mora, Yale University professor.

Areas of know-how

SEADM technology is based on the integration of commercial mass spectroscopy and two areas of proprietary know-how:

Differential Mobility Analysis (DMA). Seadm develops Differential Mobility Analyzer (DMA) tailored to replacement of LC equipments, showing excellent characteristics of MS integration, speed, sensitivity and resolution.
An ion source for ionisation of vapors, based on the Electrospray ionization (ESI). The ion source, or electrospray ionizer, readily interfaces with the Differential Mobility Analyzer (DMA), and allows on-line analysis of vapours, for DMA-MS applications.

The company holds 11 patents in the area, and has the exclusive world-wide licence for 2 patents on mobility analysis property of Yale University (USA), and sublicensed by the US company NanoEngineering.

Activities

Since 2005, SEADM has completed or is currently developing the following projects:

EXPLOSIVE TRACE DETECTION
- Industrial research activities in the field of explosive detection from 2005, all of them developed in partnership with Fundación CARTIF:
  - AROMA project, jointly funded by the Spanish Ministry of Industry (Profit program) and Ministry of Defence (Coincidente program).
  - OLFATO project, funded by the Castilla y Leon Regional Government (ADE line 4), in 2006-2007.
  - DETEV project, funded by the Spanish Ministry of Industry in 2007-2009.
  - SIMDE project, funded by the Castilla y León Regional Government (ADE line 4) in 2007-2009.
  - CARGO project, under subcontract from the related company SEDET, which started in 2008 and is currently under development.
- The company has developed a Demonstrator showing detection capability for vapour traces of explosive in the atmosphere at concentrations of 1 ppq (parts per quatrillion) .
DIFFERENTIAL MOBILITY ANALYSIS (DMA) DEVELOPMENTS
- MAIMS Program (Mobility Analysis Integrated with Mass Spectrometry), an eighteen months program which began in September 2006, is an initiative to couple a Differential Mobility Analyzer (DMA) to an API Mass Spectrometer, in order to increase its resolution capability for biological analysis. MAIMS is an international Canadeka program and is partially funded by the Spanish Ministry of Industry within the 2004-2007 I+D+i National Plan.
- VEAME Program, which began in June 2009 and is planned to last for 18 months. Its aim is to develop an electronic Differential Mobility Analyzer (DMA). VEAME is supported by the Spanish Ministry of Industry.
- EVA Program, which began in February 2010 and is planned to last for 18 months. Its aim is to couple two Differential Mobility Analyzers (DMAs) in serie, in order to obtain a mobility filtering device with a resolution in the order of 1,000.

VAPOR IONIZER BY MEANS OF AN ELECTROSPRAY CLOUD (SESI) DEVELOPMENT
- Development of an ion source for ionization of vapors based on an electrospray cloud (SESI) directly integrated to the Differential Mobility Analyzer (DMA). An internally funded program, its aim is to increased ten fold the ionization efficiency of an Electrospray source closely integrated with a Differential Mobility Analyzer (DMA).

Resources

SEADM has the following resources:

Personnel: 12 engineers.
Laboratory: Installed in Fundación CARTIF facilities, Seadm laboratories cover a 250 m2 area, and include aSciex Q-Star XL TOF mass spectrometer, a Sciex API 5000 triple quadrupole, as well as a single quadrupole Shimadzu LCMS 2010.
