Refractometers

Refractometers measure refractive index, which is often converted into a concentration measurement; typically of sugar (°Brix) for food applications or other easily useable concentration scales relative to the products being measured.

When light passes from one medium to another, the speed at which the light travels will change depending on the parameters of the materials. This principle can be seen when looking at a straw in a glass or an oarsman on the river, where the straw or oar appears to be bent at the water/air interface. The ratio or change in the speed of light is called refractive index and instruments that measure this are called refractometers. 

Bellingham + Stanley offer a range of bench-top and handheld digital refractometers to suit your requirements. 

RFM300-T Refractometers

The RFM300 now boasts a 7" touchscreen user interface with easy to use menus giving this powerful refractometer, suitable for harsh factory environments, a fresh modern look and feel.

The RFM300-T with Peltier temperature control, 3 decimal places °Brix, and a refractive index of up to 6 decimal places is suitable for measurement and control in demanding food, beverage, chemical and industrial applications due, in part, to its shallow, easy to clean prism dish with wide beam optics. Thanks to this technology the RFM300-T Series refractometers are capable of measuring non-homogenous samples such as fruit juice with pulp, opaque chemical compounds and emulsions that are normally difficult to read with other optical refractometers.

The instrument's new case is ergonomically designed so that any spills are dealt with by the sloping shape of the case or by the PEEK spill barrier that surrounds the shallow, easy-clean stainless steel prism dish.

RFM900-T Refractometers

The RFM900-T Series of Peltier temperature controlled refractometers combine latest opto-electronic principles with durability and ease of use via a touchscreen user interface.  Offering a wide refractive index range and high precision measurement to six decimals RI, the RFM970-T version is ideal for use in pharmaceutical applications operating in accordance with Pharmacopeia and FDA regulation 21 CFR Part 11; as well as in petrochemical, chemical, and aroma applications.

A new low profile sample dish and non-contact presser makes sample application and cleaning much easier than with its predecessor. Readings can be taken automatically on the replacement of the presser and up to 8000 stored results can be easily viewed in tabular form on the instrument display. Peltier temperature control and intelligent temperature management ensures readings are only taken when the sample and refractometer temperatures are both stable.

The instruments conform to a number of industry measurement standards and offer operational features that allow use in an environment controlled by FDA regulation 21 CFR Part 11. The use of a Kalrez® gasket and sapphire prism facilitates placement in the harshest measurement environments including those in the pharmaceutical, petrochemical, aroma, flavour, fragrance and other high RI sectors.

RFM700-M Refractometers

RFM700-M Series refractometers are robust, low cost, fully automatic instruments that are ideally suited to the food, sugar and beverage industries but can now be used in many other non food applications where use of temperature control is not required.

RFM700-M Series refractometers are robust, low cost, fully automatic instruments that are ideally suited to the food, sugar and beverage industries but can also be used in many other non-food applications where temperature control is not required, for example measuring sugar (°Brix) concentrations in the food processing industry.

There are three models to choose from depending on the application requirement and the budget available. The entry level instrument is the RFM712, which is especially suited for use in fruit processing plants such as in the wine, tomato and sugar industry, whilst the RFM742 is a 2-decimal place instrument ideal for use in beverage plants.

Commonly, the RFM700-M Series refractometers are supplied to operate in the °Brix scale with results temperature compensated to 20°C in accordance with ICUMSA. Additional user scales provide measurement in different formats such as various wine, Refractive Index (RI) & FSII as well as allowing custom scales to be loaded in accordance with product data. Product specific temperature compensation may also be input to the RFM700-M Series refractometers providing a corrected reading whatever the instrument temperature. Sample temperature stability is also important.

The RFM700-M Series has the ability to sense a sample being placed on the prism so that it can make a measurement "hands-free." Push-button or continuous read functions are also selectable.

TOC

Total Organic Carbon (TOC) analysis is the measurement of organic contamination levels, and is therefore an important indicator of general water quality. TOC is an effective monitoring parameter because it responds to all types of organic carbon, either dissolved or suspended in water, including compounds without a chromophore. 

OI Analytical offers bench-top systems for highly accurate laboratory analysis of spot samples collected at designated intervals and on-line analyzers that monitor influent and effluent process water streams in real time.

1080 TOC Analyzer

The 1080 TOC Analyzer processes aqueous samples for analysis of the total organic carbon (TOC), total inorganic carbon (TIC), and non-purgeable organic carbon (NPOC) content. Supporting USEPA-approved methods, Standard Methods, ASTM, DIN/ISO/CEN, and EU Methods the 1080 can analyze up to 300 samples per 24-hour period, depending upon the protocol employed, in excess of 100,000 samples per year. Principal applications include: wastewater, seawater, industrial process water, drinking water, groundwater and cooling water.

The 1080 TOC employs a multi-step analysis technique to distinguish and quantify different forms of carbon present in sample matrices and determine TOC content. The value reported as TOC is the non-purgeable organic carbon (NPOC) content. NPOC is derived by first determining, or sparging, the TIC content of a sample and then introducing the TIC-free sample into the combustion reactor to oxidize organic compound constituents.

TIC concentration is determined by acidifying a sample to a pH less than 2. Carbonates and bicarbonates in the sample dissociate, forming CO2, which is measured by a solid state non-dispersive infrared detector (SSNDIR) and reported in mass and concentration values.

TIC-free samples are Pulse-Timed injected into the reactor to perform high temperature (680 ºC) combustion over a platinum catalyst. Organic compounds are oxidized and converted into CO2, which is then quantified by the SSNDIR detector. The result is reported as the TOC content in both mass and concentration of carbon.

The 1080 TOC also supports other analytical approaches — including TC, TOC by subtraction (TC-TIC), and simultaneous determination of total bound nitrogen (TNb) using the optional TNb analysis module.

Model 1080 Features:

  • Wide operational range (50 ppb –2,000 ppm C)
  • Supports TC/TIC/TOC/NPOC analysis techniques and standard measurements
  • Patented* Smart Slide injector extends o-ring life and reduces maintenance
  • Patented* Tube Guard extends furnace tube life, and reduces maintenance

Aurora 1030W TOC Analyser

TOC for 50p*

The Aurora 1030W TOC Analyzer is ideal for the following applications: drinking water, pharmaceutical cleaning validation, municipal wastewater, ground water/surface water, process water, boiler feed water and condensate, metal plating solutions, and ultrapure water.

The Aurora 1030W TOC Analyser uses the proven heated persulfate wet oxidation technique to analyse organic contamination levels in liquid samples. The instrument can be programmed and calibrated to analyze samples containing organic carbon at levels as low as 10 ppb and as high as 30,000 ppm. In addition to its wide range, the Aurora 1030W has an extremely high daily throughput. Up to 300 samples can be analyzed in a 24-hour period (dependent on method and application).

The reaction chamber of the Aurora 1030W is thoroughly rinsed between analyses to eliminate residue from the previous sample. This ensures the Aurora 1030W maintains the low system background necessary for high sensitivity TOC measurements. This contrasts with combustion TOC analyzers in which residual salts accumulate on catalyst surfaces, degrading oxidation efficiency and causing higher blanks and background contamination.

*TOC for 50p. Cost of ownership is based on consumables required to analyse 80 samples per day over a 49 week working year. For details, contact us.
