The model 360 retains the mixing chamber and burner design which give the model 410 its renowned stability; a solid foundation to which we have added the model 420’s auto flame optimisation technology. Ease of maintenance is also retained as a key feature and five filters for Sodium, Potassium, Lithium, Calcium and Barium are supplied as standard. This is a single channel unit providing analysis of one element at a time in a competitively priced build design. The model 360 is available in three formats; 360 Nat Gas for use with low pressure Natural Gas supplies 360I for use with Propane/Butane/LPG and 360C with linearised Sodium response, for use with Propane/Butane/LPG.

Product Overview

Five element (Na, K, Li, Ca, Ba)

Single channel Analogue 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

With selected filter indicator

Safety features including fail safe flame detection and shut off, with low air pressure indicator

High sensitivity with fine manual control of air, and stable flame design

And ease of maintenance and storage

Separate pneumatic and electronic pods

Small footprint (20 x 30cm)

Easy to remove and clean filter stick

Available In Three Formats:

  • 36000009 – M360 5-ELEMENT FLAME PHOTOMETER – Propane/Butane
  • 36000109 – M360 5-ELEMENT FLAME PHOTOMETER – Natural Gas
  • Both the above are supplied with individual1000 ppm (mg/l) calibration concentrate solutions
  • 36000209 – M360C 5-ELEMENT FLAME PHOTOMETER – Propane/Butane
  • The M360C is provided with a mixed calibration concentrate 140.0/5.00/1.50 mmol/l Na/K/Li

It is important to order the correct part number to ensure fuel gas compatibility. Detector response in the 360C is “linearized” when the Sodium filter is selected; 
the 360C specification – see below – assumes samples are diluted as indicated.

 

Model 360c specification

 

 

Measurement range

  • Na Serum: 110 to 170 mmol/l
  • Na Urine 0 to 200 mmol/l
  • K Serum 0 to 10.0 mmol/l
  • K Urine 0 to 200 mmol/l
  • Li Serum 0 to 3.0 mmol/l

Linearity

  • Na Serum: within ± 2 mmol/l
  • Na Urine within ± 4 mmol/l
  • K Serum ‹ ± 0.2 mmol/l
  • K Urine ‹ ± 2 mmol/l
  • Li Serum ‹ ± 0.2 mmol/l

Reproducibility

  • Na (140 mmol/l) better than 1.5% CV
  • K (5 mmol/l) better than 1.5% CV
  • K (80 mmol/l) better than 1.5% CV
  • Li better than 2.5% CV

Dilution factor

  • Na Serum/Urine: 1 in 200 with de-ionised water
  • K Serum: in 200 with de-ionised water
  • K Urine: 1 in 1000 with de-ionised water
  • Li Serum 1 in 50 with de-ionised water

Note: The above is correct for use with Propane or Butane. Results obtained from 20 replicates of the same sample, aspirating sample for 20 seconds, then water for 10 seconds. To achieve the stated specification the flame must be alight for a minimum of 30 minutes, with diluent being aspirated. (For a brand new, newly installed unit, the stabilisation is highly likely to be greater than 30 minutes).

Note: For Li determinations; blank and standard solutions must contain similar levels of Na, K and Ca to those present in physiological samples.

Propane/Butane Specification

Model 360 Part Number 360 00 009

Operating range

Sodium is highly prone to self-absorbance in the flame above a concentration of 10 ppm.

For optimum performance the Model 360 Flame Photometer should be warmed up for 30 minutes.

Specificity

Na, K & Li interference is <0.5% value of element under analysis.

Reproducibility

<1.5%* CV for 10ppm K set to 1000 (20 aliquots sampled for 20 seconds each from a single sample). Reading taken 20 seconds after introduction and with a Blank aspirated for 10 seconds between each standard reading.
<1.0%* CV for 20 consecutive readings taken at 20 second intervals without removing the uptake tube from a 10ppm Potassium solution Set to 1000.

(*may not be achievable if fuel gas used is Natural Gas)

Aspiration rate

3-6 ml/min

Speed of analysis

Time to stability 20 seconds

Data output
