CONT

"Concentrated Grape Juice" or "Grape Juice Concentrate" a. shall be the unfermented product prepared by the concentration of the liquid obtained from sound, clean, ripe grapes; b. shall be prepared without the addition of a sweetening ingredient; c. shall be concentrated to contain not less than 30 per cent by weight of soluble grape solids as determined by refractometer at 20 degrees Celsius, uncorrected for acidity; d. shall be substantially free from crystals of salts of tartaric acid; e. may contain a residue of up to 10 mg of sulphur dioxide per kg of concentrated grape juice where the grape juice contains juice obtained from vinifera type grapes; f. may contain up to 20 mg of sulphur dioxide per kg of concentrated grape juice to prevent discolouration where the grape juice is a white grape juice and is so identified...

English

Subject field(s)
  • Scientific Instruments
  • Analytical Chemistry
CONT

The microwave plasma detector uses a microwave plasma to excite compounds and/or their microwave-produced fragments. Photometric measurement of the emitted radiation completes the detection system.

OBS

Free electrons thus produced cause the solute molecules to fragment into free atoms and diatomic molecules which give rise to spectra. The technique is limited but is suitable for the selective study of compounds containing halogens, phosphorus and sulphur atoms.

French

Domaine(s)
  • Instruments scientifiques
  • Chimie analytique
CONT

Détecteurs sélectifs. [...] Nous citerons encore les détecteurs électrochimiques permettant d'obtenir des réponses sélectives pour les composés azotés, chlorés ou soufrés, et d'autres, tels que le détecteur à ionisation d'argon ou d'hélium, détectant des traces de gaz permanents, de même que le détecteur à ionisation par haute fréquence. Pour les atomes métalliques, on pourra utiliser le détecteur à plasma excité par micro-ondes.
