Introducing MIRA Pico SeriesTM  Middle  Infrared  Laser-­‐Based  Gas  Analyzers  

   

   Next  Generation  Gas  Analyzers  Introducing  the  new  MIRA  Pico  Series  portable  middle  infrared  laser-­‐based  gas  analyzers  from  Aeris  Technologies,  Inc.  MIRA  gas  analyzers  utilize  simple  and  robust  direct  absorption  spectroscopy  using  high  resolution  tunable  lasers,  enabling  target  species  to  be  measured  in  real-­‐time  with  sub-­‐ppb  sensitivity,  ppb-­‐level  accuracy,  and  high  specificity.  MIRA  Pico  Series  analyzers  provide  performance  levels  previously  only  achieved  in  much  larger  and  higher  power  consumption  portable  analyzers.    Species  accessible  with  the  MIRA  platform  include:  

• Greenhouse  gases:  CO2,  CH4,  N2O,  H2O  • Natural  Gas:  CH4,  C2H6  • Pollutants:  CO,  H2CO  

   Core  Technologies  MIRA  series  analyzers  combine  state-­‐of-­‐the-­‐art  electronics,  solid  state  laser  sources,  and  Aeris’  unique  multipass  cell  technology  to  achieve  sub-­‐ppb  sensitivity  and  ppb  level  accuracy  in  an  ultraportable,  low  power  consumption  package.  MIRA’s  single  board  computer  efficiently  controls  all  critical  analyzer  functions,  with  industry-­‐lowest  power  consumption.    The  proprietary  sensor  engine  used  in  every  MIRA  analyzer  uniquely  achieves  a  long  absorption  path  length  in  an  extremely  small  volume,  providing  ultra-­‐high  sensitivity  and  a  fast  response  time  with  reduced  pumping  requirements.    

 

       MIRA  laser-­‐based  sensor  engine,  comprising  a  fixed,  sealed  optical  bench,  integrated  laser  and  detector  subassemblies,  and  ultra-­‐compact,  60cc,  13m  path  length  optical  multipass  cell.          

 

               Capabilities  MIRA  Pico  Series  portable  analyzers  utilize  a  compact,  pressure  stabilized  sensor  core  to  achieve  high  sensitivity  and  low  drift,  significantly  reducing  or  eliminating  calibration  requirements  in  many  field  applications.      Key  Features  include:  

• Ultra-­‐portable:  11.5”x8”x3.75”  • Sub-­‐ppb/s  sensitivity  • 10-­‐20  ppb  p-­‐p  long-­‐term  drift,  5-­‐10ppb  typical  • 3kg  (7lbs)  with  batteries    • 10Hz  intrinsic  reporting,  user-­‐defined  update  • 60cc  cell  volume,  rapid  flushing  with  small  pump  • WiFi,  Ethernet,  USB  Interfaces  • 15W  power  consumption  (ambient  conditions)  • On-­‐board  Li-­‐ion  batteries  provide  up  to  8  hours  

continuous  use    Applications  MIRA  Pico  Series  analyzers  offer  high  accuracy,  real-­‐time  monitoring  solutions  for  applications  including:  

• Natural  gas  (CH4/C2H6)  leak  detection  • Greenhouse  gas  and  pollution  field  monitoring  • Hazardous  gas  detection  • Portable  emissions  monitoring  • Calibration  of  other  field  instruments  

 MIRA  Pico  Series  portable  systems  come  in  a  compact  0.2ft3  form  factor,  the  smallest  in  the  industry.  MIRA  Pico  Series  gas  analyzers  redefine  the  state-­‐of-­‐the-­‐  art  in  portable,  laser-­‐based  gas  analysis  systems.    About  Aeris  Technologies,  Inc.  Aeris  Technologies,  Inc.  is  a  Silicon  Valley  startup  focused  on  providing  laser-­‐based  gas  analysis  solutions  to  the  chemical  sensing  marketplace.  The  Aeris  team  includes  experts  in  laser  technology,  laser  spectroscopy,  and  complete,  laser-­‐based  gas  analysis  systems.

MIRA  Pico  Series  gas  analyzers  are  based  on  mid-­‐infrared  absorption  spectroscopy,  providing  high  sensitivity  and  specificity.  Compared  to  near-­‐infrared  absorption-­‐based  analyzers  currently  on  the  market,  MIRA  mid-­‐infrared  analyzers  enable  the  same  absorption  to  be  obtained  in  a  much  shorter  path  length.  This  eliminates  the  need  for  fragile,  high  reflectivity  optics  in  the  sensor  core,  making  MIRA  analyzers  100x  less  susceptible  to  optical  contamination  than  analyzers  based  on  “cavity-­‐enhanced”  approaches.  

Typical  CH4  absorption  spectrum  obtained  with  the  MIRA  Pico  Series  Analyzer.  Spectra  are  obtained  at  a  repetition  rate  of  1kHz,  providing  real-­‐time  concentration  as  well  as  dry  mole  fraction  data  in  cases  where  water  vapor  is  measured  simultaneously.  

Typical  CH4  precision  and  long-­‐term  drift  shown  over  an  extended    period  under  typical  varying  room  temperature  conditions  (few  degrees  C).    This  level  of  stability  is  sufficient  for  many  field  applications.
