Diluter/dispenser familyHook and Tucker have introducednew liquid diluter/dispensers andcan now offer models to cater for allliquid handling procedures. Firstly,there is the Compudil DR- a twin-syringe diluter/dispenser of similarspecifications to the original ModelD, but with the additional benefit ofan RS232 interface for total computerhandling applications, in addition tofootswitch or handset operation atthe laboratory bench.

With both the D and the DR version,there are 10 different syringes avail-able to enable dispensing of anysample volume from 2-5000tl, andany diluent volume between 50 gland 25 gl. Three interchangeablevalue blocks cover all options ofsyringe or tubing sizes.

Dispensing accuracy and precisionare excellent. Actual volumes de-livered are within 0’5% of desired

290

volumes and typical performancegives CV better than 0" 1%.

Volume selection is by a four-digitthumbwheel switch. Sample volumescan be selected in 1 steps, whilstdiluent volumes are in 10 xl steps;and there are nine different operationspeeds. Alternatively with the DR, analmost infinite range of operatingprocedures can be programmed via aPC.

The budget-priced Compudil DS is asingle syringe version of the Compu-dil D with a similar technical specifi-cation and operating features. Itoffers dilution ratios of up to 250.

Lastly, and intended for routinelaboratory situations which requireaccurate and precise liquid handlingon-line, there is the new CompudilSR. This is a compact, single syringeinstrument that is supplied with achoice of nine interchangeablesyringes between 50 gl and 25 tl togive a wide choice of volumes andrations. It is driven by either a simpleset ofcommands, via a RS232C seriallink, or one of nine user-definedprograms. Coupled with its inertfluid lines, these features make the

Monochromator

The 0"25 m Czerny-Turner Mono-chromator is now available as aseparate item for general appli-cations. The optical design is basedon a 0"25 m Czerny-Turner Mono-chromator with a 1200 per mmgrating blazed at 300 nm; giving a

reciprocal dispersion of 3 nm/mm.

Wavelength selection is by means ofstepper motor scanning system,which can be controlled eitherthrough a keypad with digital indica-tion of wavelength, or through anIBM PC compatible computer, inwhich case the wavelength is shownon the computer screen. The mono-chromator housing is designed toaccommodate a photomultiplier,thereby minimising stray light prob-lems. The spectral range of thesystem is 186-930 nm and the aper-ture is fl 0.

Six slit positions between 0’025 mmand 1’0 mm are provided. The slitmechanism is driven by a secondstepping motor.

The Monochromator housing isprovided with nitrogen purge facili-ties to maximize operation in theultra-violet region.

Oxidative stability of fats and oils

The Metrohm 679 Rancimat willoxidize in air, at elevated tempera-tures, samples of edible oils or fats. Aconductivity measuring cell is usedfor the continuous detection of thevolatile carboxylic acids liberated.The 679 then prints out the experi-mental curves continuously, on up tosix samples at a time, using theinbuilt printer.

The Rancimat has a temperaturerange from 50 to 220 C, allowing thedetermination of both sensitive andvery stable oils.

In comparison with the traditionalAOM test, the Rancimat methodoffers considerable savings in time.The AOM test also calls for periodicsampling and titrations which alsooften require sample treatment and isexpensive.

Applications of the Rancimat are notonly restricted to the rancidity ofedible oils, but also to the processedand confectionery food industries, forexample baby food, chocolate, icecream etc.

mass spectometer linked to a liquidchromatograph tbr separation. Ionsare created at atmospheric pressure,rather than inside the vacuumsystem, with little or no heating- a

technique known as AtmosphericPressure Ionization and applicable topolar, thermally labile molecules.

The ions produced are transferred tothe mass spectrometer, which ismaintained under high vacuum, bymeans of a specially-designed inter-

face. This permits the ions to pass,while excluding the bulk of thesample and avoids the need to pumplarge volumes of solvent.

The technique is particularly appro-priate to the analysis of pharma-ceutical products, surfactants andfine chemicals.

The API III incorporates two massanalysers with a collision cellbetween them. This arrangement
