New: Gas Analysis for High-Speed Processes

The new hyperLine expands our fami­ly of gas ana­ly­zers with an excep­tio­nal­ly fast solu­ti­on: With a respon­se time of appro­xi­m­ate­ly T90 = 30 ms at a gas flow rate of only 0.5 L/min, the­se side-stream ana­ly­zers can detect even tran­si­ent chan­ges in gas concentration.

Applications Involving Rapid Changes in Gas Concentration

The hyperLine was deve­lo­ped for mea­su­ring rapid pro­ces­ses in indus­try and medicine.

One ear­ly appli­ca­ti­on illus­tra­tes just how chal­len­ging such mea­su­re­ments can be: deter­mi­ning the CO2 con­tent in the exha­led air of dol­phins. During a forced exha­la­ti­on (“Forced Expi­ra­to­ry Breath”), the ani­mals exha­le near­ly their enti­re lung volu­me in just 200 mil­li­se­conds. By com­pa­ri­son, this pro­cess takes about 6 to 12 seconds for humans.

Other appli­ca­ti­ons include:

  • Eddy cova­ri­ance for mea­su­ring trace gas distributions:
    CO2, H2O, or CH4 mea­su­re­ments are cor­re­la­ted with tur­bu­lent wind speeds.
    Gases: CO2, H2O, CH4
  • Com­bus­ti­on engi­ne development:
    Rapid com­bus­ti­on pro­ces­ses can be mea­su­red and visua­li­zed in the exhaust gas.
    Gases: CO2, CO
  • Gas disper­si­on in wind tunnels:
    Fluc­tua­ting tra­cer gas con­cen­tra­ti­ons are mea­su­red to stu­dy the tur­bu­lent disper­si­on of pollutants.

 

With a con­ti­nuous data trans­mis­si­on rate of 200 mea­su­re­ment values per second and a reso­lu­ti­on of 16 bits, the hyper­Line accu­ra­te­ly dis­plays the­se rapid con­cen­tra­ti­on chan­ges. Alt­hough CO2 and CO are typi­cal mea­su­re­ment gases, the mea­su­re­ment prin­ci­ple can also be appli­ed to other gases in the goSen­se ana­ly­zer lineup.

Challenging Pneumatics

With mea­su­re­ments this fast, the enti­re gas path plays a cru­cial role: the sup­p­ly tubing, fil­ter, and pump all influence whe­ther a sud­den chan­ge in con­cen­tra­ti­on in the sup­p­ly line is “sme­ared out” and how well brief chan­ges in con­cen­tra­ti­on are pre­ser­ved. That is why we offer the hyperLine with an optio­nal gas sam­pling kit.
