Equipments Used to Measure Body Temperature01:13

Equipments Used to Measure Body Temperature

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
Amperometry: Overview01:10

Amperometry: Overview

Amperometry is a technique commonly used to measure the concentration of specific analytes in a solution by monitoring the electric current generated during an electrochemical reaction. It involves applying a constant potential between a working electrode and a reference electrode to measure the resulting current, which is proportional to the concentration of the analyte. The Clark oxygen electrode operates based on this principle of amperometry. It consists of a cathode and an anode enclosed...
Gas Chromatography: Types of Detectors-I01:21

Gas Chromatography: Types of Detectors-I

There are different types of detectors used in gas chromatography, each with its own specific properties that make it suitable for detecting certain types of analytes. The most commonly used detectors in GC are thermal conductivity detector (TCD), flame ionization detector (FID), and electron capture detector (ECD).
TCD is the earliest and most widely used detector that operates by measuring the changes in the thermal conductivity of the carrier gas. When a sample compound enters the detector,...
Capillary Electrophoresis: Instrumentation01:20

Capillary Electrophoresis: Instrumentation

Capillary electrophoresis instrumentation typically consists of several key components. A high-voltage power supply generates the electric field necessary for the separation by connecting to an anode (the positively charged electrode) and a cathode (the negatively charged electrode) located in buffer reservoirs at each end of the capillary tube. The system includes a sample vial, a fused silica capillary tube coated with polyimide for mechanical strength through which the sample components...
Electronic Distance Measuring Instruments01:30

Electronic Distance Measuring Instruments

Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over short distances...

Area of Science:

  • Materials Science
  • Public Health
  • Engineering

Background:

  • The COVID-19 pandemic highlighted the critical role of face masks in infection control.
  • Ensuring the quality of filtering facepiece masks is vital for protecting healthcare personnel.
  • Certified penetrometers for mask testing are expensive and were scarce during the pandemic.

Purpose of the Study:

  • To develop simple, inexpensive, and rapid methods for testing filter penetration of face masks.
  • To provide accessible tools for assessing mask quality, especially during public health crises.
  • To validate these new methods against a certified penetrometer.

Main Methods:

  • Two novel methods were developed using an electronic cigarette as the basis for testing.
  • Method 1 utilized a precision scale to measure filter penetration.
  • Method 2 employed a light scattering detector for filter penetration assessment.

Main Results:

  • Both developed methods demonstrated a good correlation with results from a certified penetrometer.
  • The methods were validated using filter samples with penetration ranging from approximately 2% to 60%.
  • The developed techniques provide a quick and reliable estimation of filter penetration.

Conclusions:

  • Simple, fast, and affordable methods for filter characterization are valuable for ensuring mask efficacy.
  • These methods can help identify faulty masks and mitigate associated health risks.
  • Broadly available testing solutions are crucial for public health preparedness.
