    Product Overview

    All three Models of 410 Flame Photometer come with a preloaded filter stick which houses a maximum of three element filters. The filter stick is easily removed and replaced within the chimney housing (no tools required) and as such it is a relatively simple operation to introduce alternative element specific filters. Filters available for use with all Model 410’s include:

    Sodium, Potassium, Lithium, Calcium, Barium, Strontium, Rubidium and Caesium; the most extensive range available from any Flame Photometer Manufacturer.

    The Model 410 Classic Flame Photometer (475 41 200) comes with Sodium, Potassium and Calcium filters. The “Classic” design is the one developed by Corning some 30 years ago. We still manufacture this highly successful unit due to popular demand. The Model 410 Classic Flame Photometer has Sodium, Potassium and Calcium  NIST traceable 1000 ppm standard concentrates for each of those analytes (6 x 100 ml). We have expanded the Model 410 Classic’s utility by introduction of the:

    Models 410 Industrial and 410C Flame Photometers ; both come with a Digital Interface fitted as standard. The Digital Interface allows connection to a serial printer or computer for result collection.

    The Model 410 Industrial Flame Photometer (475 41 201)

    Flame Photometry is the technique of choice for the measurement of Sodium, Potassium and Calcium in all sample types in: Mineral Extraction, Oil Industry, Paper Industry, Pharmaceuticals, Soil Analysis, Utilities, Food & Beverage, Chemical Manufacture and Fertilisers. The Model 410 Industrial Flame Photometer with digital output, for printer or PC connection, also has Sodium linearisation capability to allow higher concentrations of Sodium (to 20 ppm) to be directly measured using a single point calibration. That facility can be switched on or off according to the operator’s preference or protocol for Sodium determinations. The Model 410 Industrial Flame Photometer has Sodium, Potassium and Calcium specific filters and NIST traceable 1000 ppm standard concentrates for each of those analytes (6 x 100 ml).

    Model 410C Flame Photometer (475 41 301)

    For biological samples, Flame Photometry is the most sensitive and robust method for the determination of Sodium, Potassium and Lithium. The Model 410C Flame Photometer is delivered with Na, K and Li filters pre-fitted and an appropriate multi-element calibrator in mmol/l. (1 x 100ml). The Model 410C instrument is also fitted with a Digital Interface and Sodium linearisation facility allowing direct, straight line, calibration of clinically significant concentrations of Sodium, as well as Potassium and Lithium, following suitable dilution. (Sherwood’s Model 805 Continuous Flow Diluter, used together with the Model 410C Flame Photometer, gives nominal sample dilution ratios of 1:200 and 1:50. It has been designed to give consistent dilution of calibrator and samples to the Flame Photometer).

    Both Model 410 Industrial and Model 410C Flame Photometers can be further enhanced by the use of Sherwood’s Model 410 BlueNotes software (410 66 000) and Model 860 Autosampler (860 00 009). Fully integrated and automated systems are possible, even for the Model 410 Classic Flame Photometer via our Update and Automate Modules and packages. See BlueNotes 410 Software in Flame Photometer Accessories on main Flame Photometer product page.

    OPERATING RANGE

    Sodium is highly prone to self- absorbance in the flame above a concentration of 10 ppm. The Digital Interface/Lineariser Module accessory (see above) will extend the linear response to 20ppm.
