A small crystal, such as quartz, is coated with a stationary phase material and placed at the end of the g.c. column; as solutes are eluted from the column they pass over the coated crystal and give rise to sorption and desorption on the crystal with corresponding frequency changes in the piezo-electric effect related to the quantity of material sorbed.  1, record 1, English, - piezo%2Delectric%20detector

Headspace sampling. Traditional methods for g.c. [gas chromatography] studies on the ethanol content of body fluids, particularly blood and urine, have involved either direct column injections, with the inherent possibility of blocking the column with solid deposits, or preliminary extraction and/or distillation. The technique of headspace sampling was introduced in order to obviate these sampling problems.  1, record 2, English, - headspace%20sampling

Quand on veut analyser des vapeurs, des odeurs de produits quelconques, que l'on appelle des flaveurs, on est amené à vouloir les concentrer quelque peu pour se placer dans le domaine possible de sensibilité des détecteurs. On a alors recours à la technique de l'espace de tête (head-space), dans laquelle l'échantillon solide ou liquide est placé dans un pilulier de faible capacité, obturé par une capsule élastomère.  2, record 2, French, - technique%20de%20l%27espace%20de%20t%C3%AAte

A device by means of which a liquid or gaseous sample is introduced directly into the chromatographic column or is swept into the column by the mobile phase.  3, record 3, English, - injection%20port

Record number: 3, Textual support number: 1 CONT

An injection port is necessary in all g.c. [gas chromatography] and h.p.l.c. [high-performance liquid chromatography] systems in which syringe injection is employed. The injection port joins the top of the column to the mobile phase supply line, and has a third outlet through a small orifice covered by a self-sealing septum. Injection of samples is done by inserting the hypodermic syringe containing the sample through this septum so that the point of the needle is immediately above the head of the column. Design of the injection port must be such that it can be maintained at a uniform temperature and will possess a very small dead volume.  4, record 3, English, - injection%20port

Chambre d'injection pour liquides ou solutions. C'est le système le plus utilisé [...] le gaz porteur, de préférence préchauffé, entre dans une chambre chauffée, obturée par une pastille d'élastomère, le septum, qui assure l'étanchéité. À l'aide d'une seringue hypodermique de petite capacité, on pique au travers de la membrane, de telle manière que l'extrémité de l'aiguille arrive au-dessous du niveau de l'arrivée du gaz porteur, puis on pousse le piston pour réaliser l'injection. La condition demandée à la chambre d'injection est d'avoir un volume interne aussi petit que possible, pour limiter les volumes morts de l'appareil. Pour assurer la vaporisation instantanée de l'échantillon, l'injecteur est habituellement maintenu à une température au moins 30 °C plus élevée que celle du four contenant la colonne.  4, record 3, French, - chambre%20d%27injection

Any regular change occurring in the baseline signal from the detector in g.c. [gas chromatography] or h.p.l.c. [high-performance liquid chromatography]. It commonly arises from changes in the flow rate of the mobile phase or from deterioration of the detector such as might occur if the stationary phase is bleeding off the column.  2, record 4, English, - baseline%20drift

[Detector drift] is represented as a continuous up-scale or down-scale excursion of the baseline, which tends to camouflage both noise and small peaks.  3, record 4, English, - baseline%20drift
