    Introduction
    Sherwood Scientific M425 flame photometer from Wolflabs. The Model 425 Flame Photometer (475 42 500) expands upon capability of the Model 420 Flame Photometer with addition of an additional detector and filter for Calcium determination.

    Features and benefits
    - Readings on both channels are linear over the working range.
    - There are several monitoring and control functions included in the firmware driving the model 420 thus measurements can only be made after blanking and calibration.
    - Can operate in Continuous or Peak mode. In Continuous mode the instrument displays the current value on each channel and through the analogue ports. An instantaneous reading can be printed at any time. In Peak mode the unit automatically detects a stable reading for transfer to a printer or computer and the display is frozen until the next sample is introduced.
    - The model 425 expands upon capability of the model 420 with addition of an additional detector and filter for Calcium determination. It also offers the “301 mode” feature which allows connection to a number of the more popular continuous flow systems.
    - Both the 420 and 425 have RS232 output for printer or computer connection and are compatible with our model 860 Autosampler for unattended sample analysis.
    - Both models may be used with the model 805 continuous flow diluter, again in-conjunction with or without the model 860 Autosampler.

    Introduction
    Sherwood Scientific M420 flame photometers from Wolflabs. The Model 420 Clinical Flame Photometer was developed from the Single Channel Model 410 Flame Photometer, with the objective of improving productivity and analytical performance, when measuring Sodium and Potassium. It is available in Clinical (475 42 000) or Industrial (475 42 100) format with appropriate NIST traceable calibration solution concentrates.

    Features and benefits
    - Dual Channel operation, allowing both Sodium and Potassium to be calibrated, measured and displayed simultaneously.
    - The Model 420 Flame Photometer retains many of the Model 410's attributes: ease of use, ease of maintenance and stable flame design but is enhanced with auto flame optimisation, internal standard referencing and on-board firmware to achieve significant improvement in sample throughput and precision.
    - The time taken to set up and calibrate the instrument is much reduced; achieved by automatic ignition and optimisation of the flame conditions.
    - The analytical performance is improved by the use of a Lithium Internal Standard signal which compensates for fluctuation in flame conditions.
    - There are several monitoring and control functions included in the firmware; thus measurements can only be made after blanking and calibration.

    Introduction
    Sherwood Scientific M360 flame photometer from Wolflabs. The model 360 retains at its heart, the well respected mixing chamber and burner design which give the model 410 its renowned stability and performance a solid foundation to add the model 420’s auto flame optimisation technology to. Ease of maintenance has been retained as a key feature and in response to current market trends five filters for Sodium, Potassium, Lithium, Calcium and Barium are standard. Available as a single channel analogue unit in a competitively priced build design, the model 360 makes our proven stable flame and easy to maintain designs available to a greater number of analysts who will gain a better analytical experience than they currently do from operating low cost units.

    Features and benefits
    - Five element (Na, K, Li, Ca, Ba) single channel flame photometer
    - Ergonomic design with front loading, unobstructed sample work area, with removable tray for easy cleaning
    - With ease of use resulting from auto ignition and flame optimisation
    - Peak picker for presenting unambiguous readings and selected filter indicator
    - Safety features including fail safe flame detection and shut off
    - High sensitivity with fine manual control of air, and stable flame design
    - Ease of maintenance and storage
    - Separate pneumatic and electronic pods 
    - Small footprint (20 x 30cm) 
    - Easy to remove and clean filter stick

Chloride analyser Sherwood Scientific M926
 

Designed for the determination of chloride ions, the Sherwood Scientific Chloride analysers are an instrumental analogue of “Argentimetry”; the traditional titrimetric methods using silver nitrate reagent. Like those classic methods, the 926 and 926S rely on formation of the insoluble salt, silver chloride. 


The importance of chloride determination was realised well over a century ago, with many variations and changes being made in order to improve detection limits and selectivity. Research into chloride analysis was conducted by Gay-Lussac (1832), Levol (1853), Mohr (1856) and Volhard (1874). Their findings are the basis of methods still in common use today. 

The first instrument using these techniques was developed in the 1960’s by Cotlove at the AMINCO Company. The 926 analysers developed from that first instrument are now exclusively manufactured in Cambridge, UK by Sherwood Scientific Ltd.

KEY APPLICATION AREAS

Industrial Model 926

The measurement of Salt (Sodium Chloride) in the Food and Dairy Industry is universal. The ability to read directly, Salt concentration and the automatic endpoint detection system has made the 926 the instrument of choice for food manufacturers and analysts throughout the world.

Salt and salinity also represent serious contamination in many industrial processes. The sensitivity of the coulometric method enables ppm range measurement in boiler feed water; polymer washes; bore-hole slurries as well as soil-salinity studies. The 926 is intended for general laboratory use and is calibrated in ppm (mg/l) chloride. The Select Button offers the immediate conversion of chloride content into mg% Salt (Sodium Chloride) of the original sample*.
* assumes ratio 1g of sample to 100ml diluent

Clinical Model 926S
Raised chloride concentration in sweat of young children is a Cystic Fibrosis indicator. The 926S is intended for chloride measurement in biological samples and calibrated in mmol/l. The 926S can accept original samples of as little as 20μl and from all types of sweat generators. The Select Button switches between sample volumes of 20ul or 100ul.
