High-Performance Liquid Chromatography: Instrumentation

High-Performance Liquid Chromatography: Instrumentation

High-performance liquid chromatography, or HPLC, is an analytical technique that separates liquid samples under high pressures. An HPLC instrument consists of glass bottles for storing solvents called mobile phase reservoirs. HPLC-grade solvents are used to maintain high purity, and the dissolved gases are removed using a degasser, such as a vacuum pumping system or sparging with helium. The solvents are then pumped into the analytical column using a screw-driven syringe or reciprocating pumps.

Background:

Bioaerosols, particles of biological origin, constitute a significant part of atmospheric particles.
These bioaerosols contain unique biochemical information specific to their source organisms.
Understanding indoor bioaerosol composition is crucial for assessing human impact on indoor environments.

Purpose of the Study:

To investigate the potential of bioaerosol analysis for identifying and differentiating indoor environments based on human occupation levels.
To establish identifiable patterns or 'fingerprints' in bioaerosols linked to specific occupancy.
To assess the feasibility of using bioaerosol signatures to distinguish between high-traffic and low-traffic indoor spaces.

Main Methods:

Collection of air samples from indoor environments with varying human traffic.
Direct human skin sampling for comparative analysis.
Quantification of total suspended particulate matter and total aerosol protein concentration.
Analysis of aqueous aerosol extracts using High-Performance Liquid Chromatography (HPLC) to detect biochemical signatures.

Main Results:

Total aerosol protein concentrations varied between 0.03 and 1.2 μg/m³ across sampled environments.
Distinct biochemical patterns were observed in bioaerosol samples.
High-Performance Liquid Chromatography enabled the differentiation of occupation-related signatures from background environmental factors.

Conclusions:

Bioaerosol fingerprinting is a viable method for identifying the source and level of occupation in indoor environments.
The study demonstrated that distinct bioaerosol profiles can differentiate between environments with different human traffic levels.
A 97% confidence interval was achieved in distinguishing between the two tested environments, highlighting the effectiveness of this approach.
