Product Description: Model 1381 EI-DVI Microprocessor Flame Photometer:
The Microprocessor Flame Photometer, Model 1381, is an ideal instrument designed for the determination of essential elements, including Sodium, Potassium, Calcium, and Lithium. It is highly useful for both medical and laboratory applications. This instrument utilizes the latest microcontroller technology and advanced engineering techniques to ensure enhanced accuracy and reproducibility in results.
Key Features and Advantages:
This unit is characterized by its user-friendly design and advanced analytical capabilities:
• Microcontroller Technology: Highly accurate measurements are achieved through the use of microcontroller technology.
• Direct Results: Provides results directly in both ppm and meq.
• Calibration: Features 3-Point calibration using curve fitting software to ensure reliable readings.
• User Interface: Equipped with soft touch membrane keys for ease of operation.
• Applicability: Extremely useful for medical and general laboratory use.
Operating Mechanism:
The Model 1381 operates by aspirating the sample solution through an axial flow type automiser. The sample, combined with dry oil free air and fuel (LPG), is mixed in a mixing chamber. This mixture is then sprayed into the flame as a very fine mist. The concentration of elements present causes a change in the color of the flame.
Radiations emitted from the flame pass through the sensing system and a specific narrow band interference filter, allowing only the characteristic radiation of the element being measured to reach the photo-detector (Silicon Photodiode). The resulting output from the photo-detector is then processed by the internal microcontroller, and the final results are displayed digitally.
