5. Indoor Air Quality (IAQ) Assessment and Consultancy Services

We spend more than 70% of our time at homes, in offices and other indoor environment. Poor indoor air quality can lead to discomfort, ill health (e.g. headache, itchy eyes, respiratory difficulties, skin irritation, nausea and fatigue), and, in workplace, absenteeism and lower productivity. Children, elderly and those with existing respiratory or heart disease are more susceptible to the effects of poor indoor air quality. Good indoor air quality safeguards the health of the building occupants and contributes to their comfort and well being.

Our indoor environment may contain a lot of air pollutants. The air pollutants that are of major concern in Hong Kong are:

  • Carbon dioxide and biological contaminants from people, pets, and plants;
  • radon from building materials;
  • volatile organic compounds from consumer products such as cosmetics, pesticide, cleansing agent, etc.;
  • formaldehyde from pressed wood products such as furniture; and
  • environmental tobacco smoke from smoking

As the founders of the Akos have extensive knowledge and experiences in both academic research and real estate assessment, she provide the most competent group for indoor air quality assessment and energy auditing.

6. Laboratory Testing Services on Air Samples, Water Samples and Materials Samples

We offer consulting, sampling, analysis, result interpreting and reporting of various testing substances, including drinking water, waste water, fuel oil, soil and sludges and various gases parameters.

Testing instrument to be employed includes:

Standard Testing Packing includes:

I. Scanning electron microscopy (SEM)

Microscopic examination of solid sample provides a powerful tool in determining the morphology of the testing sample including shape and size.

II. Energy Dispersive Analysis by X-ray diffraction (EDAX)

The present of the metal and the other inorganic component could be detected and identified, the elemental composition would be quantified.

[ BACK ]

III. Powdered X-Ray Diffraction (XRD)

Powdered X-ray diffraction provides a powerful tool on determination the crystallinity of a solid. By comparing the Powdered X-ray Diffraction pattern with library from Inorganic Chemical Structure Database (ICSD), the chemical formula of the crystalline solid could be determined.

IV. Total Organic Carbon

An oxidizer and an acid are added to the testing sample. The acid would react with bicarbonate and carbonate ions present in the testing sample and release carbon dioxide (CO2). The CO2 released from bicarbonate and carbonate ions represented the Total Inorganic Carbon (TIC) in the sample. The testing sample is then subjected to ultra-violet (UV) radiation, which would react with the oxidant and break down all remaining carbon bonds in the testing sample to release CO2. The CO2 released from both the acid reaction and the UV radiation represents all the Total Carbon (TC) released from the testing sample. TOC is then obtained by subtracting TIC from TC.

V. Particle Size Analyzer

Particle size distribution by particle size analyzer - measuring range 0.04 - 2000 £gm laser particle size

[ BACK ]

VI. Bet Surface Area Analyzer

Surface area and pore size determination

VII. Elemental Analysis by ICP

(inductively-coupled plasma) detects up to 24 metals, measuring less than 5 microns in size. Metals include iron, chromium, nickel, aluminum, copper, lead, tin, cadmium, silver, titanium and vanadium. Contaminant Metals include silicon, sodium, potassium, molybdenum, antimony, manganese, lithium, boron, magnesium, calcium, barium, phosphorous and zinc could be detected.

VIII. Thermo-Gravimetric Analysis (TGA)

The change of weight of testing sample upon elevation of temperature would be monitored. This analysis is capable to detect oxidation by weight gain and water evolution by weight loss upon the elevation of the temperature.

VIII. Fourier Transform Infrared Spectroscopy (FTIR)

FTIR is most useful for identifying chemicals that are either organic or inorganic. It can be utilized to determine some components of an unknown mixture. It can be applied to the analysis of solids, liquids, and gasses.

A. Standard Fuel Oil Testing Package

Available testing include spot test, water amount, sulfur amount, chloride amount, sediment by extraction, ash amount and X-ray analyses on ash for dominate Element. All testing were carried out by ASTM standard testing method.

B. Standard Resin Sample Testing Package

  • Bead Count - The percentage of the whole beds, cracked beads and broken beads
  • Photo - Microscopic photo of a representative sample
  • Particle size (effective size, mean diameter and uniformity coefficient) - Distribution percentage of various beads by size
  • Moisture content - The percentage of mixture content of beads and compares t moisture content of comparable new resin
  • Organics - The amount of extractable organics on Anion resin to determine potential for organic fouling
  • Reversible swelling - The expansion of an ion exchange bead which occurs when the reactive groups on the resin are converted from one form to another
  • Total exchange capacity - The cation exchange capacity represents the total amount of exchangeable cation that the resin can adsorb, while then anion exchange capacity represents the total amount of exchangeable anion that the resin can adsorb.
