Process Analysis Specialists
|
DHC Analysis is an analytical consulting laboratory specializing in NIR, FT-IR for industrial analyses. We develop calibrations by using chemometrics techniques, develop new methods, carry out feasibility studies, provide training develop and write software applications. We have a combined total of over 50 years experience in research, applied analysis, and implementation. |
DHC Analysis maintains a complete laboratory with state-of-the-art spectroscopic equipment.
FT-IR and FT-NIR spectrometers - portable systems
Spectroscopic accessories for research and analytical development work:
Gas cells - ambient to 300oC; path length 1 cm to 10
meters
ATR: horizontal, flow through,
micro
Diamond cell: high pressure and high temperature
applications
Diffuse Reflectance: reaction chamber (-100 to 900
- 1500psi)
Emission
External reflection
Flow through cells.
DHC Analysis develops calibrations for different analytes; we undertake the whole process of completing the basic research needed to develop robust calibrations. We investigate the sampling possibilities, often developing new strategies that best suit the client's needs, apply chemometrics methods to demonstrate and validate calibrations.
Examples:
|
Isocyanate |
Multicomponent gases |
Octane number |
|
Moisture |
Iodine value |
Hydroxyl value |
|
Viscosity |
Molecular weight |
Degree of Cure |
We also develop and implement pass/fail and overall compositional analysis calibrations and offer services for improving and maintaining existing calibrations.
Feasibility Studies - On-site
Research
|
DHC Analysis can bring equipment to a plant or laboratory for on-site feasibility studies. Feasibility studies are often needed to establish the viability of certain analysis. Issues such as sampling strategy, cell fouling, time response, interferences, user interface, can only be studied on-site. We have completed many feasibility studies where the sample just cannot be removed, preserved, and analyzed in a laboratory. |
Examples:
Monitoring
of High Temperature Furnaces
Environmental applications
Process Gases, chemical
reactors
High pressure - high
temperature polymerization reactions
Dangerous or corrosive streams
(HCN, Cl2, COCl2 ... )
We provide on-site training courses in FT-IR spectroscopy, quantitative analysis, chemometrics and process analysis. These courses are tailored to the specific needs of the clients.
Training courses in our facilities can include hands-on sessions with most spectroscopic accessories.
We use all of the chemometrics techniques available for quantitative analysis and also develop new methods and techniques to enhance the current methods.
Software available:
Mutli-linear regression
Principal Component Analysis
and Regression
Partial Least Squares
Cluster Analysis
Spectral Process Software
Complete statistical analysis
packages
On-line and off-line Process
Analysis Packages.
DHC Analysis develops, writes, and maintains software packages for QA/QC applications.
We also write software
applications for automatic on-line collection of spectra, analysis and data
reporting. These programs include communication with other computers as well
as DCS systems.
