Product introduction   
LSPEC  2000  Highly  sensitive  and  rapid  gas  chromatography  analyzer  can  quantitatively  detect  ppb~ppm  gaseous  (or vapor)chemicals.The   instrument   is   based   on   fast   gas   chromatography   analysis   technology,using   highly   sensitive surface   acoustic   wave    sensor,with   high    detection   sensitivity,small   measurement    error,short   detection    time,good repeatability,high  reliability,can  authorize  users  to  add  database,to  achieve  a  variety  of  substances  wide   spectrum
The  instrument  adopts  ultra-sensitive  surface  acoustic  wave  sensor  to  reflect  the  concentration  characteristics  of substances  through  the  frequency  changes  caused  by  substances  flowing  through  the  crystal  surface  of  the  sensor. After  each  analysis,high-temperature  baking  can  be  used  for  cleaning  to  ensure  the  accuracy  of  the  next  analysis.     The  instrument  offers  a  variety  of  portable  accessories  for  easy  measurement  by  users,making  it  ideal  for  laboratory

Technical    specification:
Surface acoustic wave sensor can realize the concentration or mass measurement of volatile and semi-volatile organic   matter    gas,with   high    precision,small   volume,low    power    consumption,fast   response    and   other characteristics,when  the  gas  through  the  sensor,sensor  surface  deposition  gas,causing  mass  change,thereby causing the resonant frequency change,after mixing,The output can reflect the output signal of the deposited gas mass of the current qas sensor,and then indirectly reflect the current qas concentration.

It can be widely used in chemical agents,drugs,explosives,water quality,food detection and other fields.
