Record 5 1996-03-07

English

Subject field(s)
  • Analytical Chemistry
CONT

Titration detector. The visual or automatic titration methods of James and Martin provided techniques for the titration of chromatographically separated volatile monocarboxylic acids. In the presence of an indicator, the titration can be followed visually or automatically recorded. With the automatic titration buret, the separated acidic or basic components in the carrier gas pass directly into the titration cell. A suitable colorimetric indicator... is used with a photoelectric relay to control the addition of titrant from a syringe-type dispensing buret, the plunger of which is coupled to a recording pen.

OBS

Mc Innes [improved the automatic titrator by including] a polyethylene gland [which incorporated] a mercury seal for the recording buret, an automatic switch-off device for the apparatus, and a photoelectric unit which provided stable and full control for dispensing titrant.

Record 6 1985-01-15

English

Subject field(s)
  • Metrology and Units of Measure
CONT

The gas indicator must be installed downstream of the meter. In empty-hose measuring assemblies, the gas indicator may be in the form of a weir-type sight glass and may also be used as the transfer point.

French

Domaine(s)
  • Unités de mesure et métrologie
CONT

Le dispositif indicateur de gaz doit être placé en aval du compteur. Dans les ensembles de mesurage fonctionnant flexible vide, le dispositif indicateur de gaz peut être réalisé sous la forme d'un viseur de trop-plein et servir simultanément de point de transfert.

Record 7 1985-01-15

English

Subject field(s)
  • Metrology and Units of Measure
CONT

The gas indicator may be fitted with a bleed screw or with any other venting device when it forms a high point of the pipework. No pipe must be connected to the venting device. Flow indicators(e. g. spinners) may be incorporated in gas indicators provided that such devices do not prevent observation of any gaseous formations which could be present in the liquid.

French

Domaine(s)
  • Unités de mesure et métrologie
CONT

Le dispositif indicateur de gaz peut être muni d'une vis de purge ou de tout autre dispositif de purge lorsqu'il forme un point haut de la tuyauterie. Aucune canalisation ne doit être raccordée au dispositif de purge. Il est autorisé d'incorporer dans le dispositif indicateur de gaz des dispositifs permettant de rendre visible le courant de liquide (par exemple des spirales ou des roues à ailettes), pourvu que ces dispositifs n'empêchent pas l'observation des formations gazeuses contenues éventuellement dans le liquide.
