Flame Photometry: Lab01:16

Flame Photometry: Lab

290
In a flame photometer, when a solution like potassium chloride is aspirated into the flame, the solvent evaporates, leaving behind dehydrated salt. This salt dissociates into free gaseous atoms in their ground state. Some of these atoms absorb energy from the flame, leading to their excitation. The excited atoms return to the ground state, emitting photons at characteristic wavelengths. Because only electronic transitions are involved, the resulting emission lines are very narrow. The intensity...

Flame Photometry: Overview

682
Flame photometry, also known as flame emission spectrometry, is a technique used for the qualitative and quantitative analysis of elements present in a sample using a flame as the source of excitation energy. The concept of flame photometry was realized in the early 1860s by Kirchhoff and Bunsen, who discovered that specific elements emit characteristic radiation when excited in flames. The first instrument developed for this purpose was used to measure sodium (Na) in plant ash using a Bunsen...

Area of Science:

  • Optics and Photonics
  • Thermal Measurement Science
  • Materials Science

Background:

  • Accurate non-contact temperature measurement in small or confined spaces is challenging due to limitations in spatial resolution and emissivity dependence of conventional methods.
  • High spatial resolution and emissivity independence are critical for applications like microthermography.

Purpose of the Study:

  • To develop and evaluate two-color optical fiber (OF) pyrometers for high-resolution, emissivity-independent temperature measurements.
  • To assess the feasibility of using standard single-mode (SMF) and multi-mode optical fibers (MMF) for microscale thermal analysis.

Main Methods:

  • Utilized two-color optical fiber pyrometers with small core diameter and low numerical aperture SMF and MMF.
  • Generated precise temperatures (approx. 340 °C) on microscale objects (0.25 mm diameter) using a patterned microheater.
  • Measured temperatures at a 1 kHz sampling rate, linearized in the 250-500 °C range, and compared with an industrial infrared camera.

Main Results:

  • Achieved micrometer-range spatial resolution, independent of material emissivity.
  • Demonstrated successful temperature measurements of small objects (250 µm) with high accuracy.
  • Confirmed that optical power gathered is distance-independent until the optical fiber spot size exceeds the object diameter (0.9 mm for SMF, 0.4 mm for MMF).

Conclusions:

  • Two-color OF pyrometers offer a viable solution for accurate, high-resolution temperature measurements in microscale and confined environments.
  • The technique is suitable for applications requiring emissivity-independent measurements, such as microthermography and thermal gradient analysis.
  • The distance independence of optical power collection within specific limits enhances the practicality of OF pyrometers for microscale thermal sensing.
