The laboratory is housed within a temperature controlled environment to maintain thermal stability of both the reference standards and instruments under test.

We realize the performance and accuracy of your mechanical, dimensional and physical test equipment is critical to your organization success so we use high quality, reliable reference standards for our calibration tasks. We pride ourselves on providing professional mechanical calibration services to ensure your measurement instruments are accurate, reliable and traceable. Due to the frequent handling, mechanical shock and exposure to various atmospheric conditions, it is inevitable that mechanical instruments will be subject to drift. To understand this drift during its’ operational service, a regular calibration schedule is required to determine the measurement shift between subsequent calibrations and to determine tolerance limits for the measurement uncertainty budget. Force Gauge Calibration in tension and compression up to 50 kN for the calibration of load cells, force gauges and push/pull gauges.

  • Chromatography and Separation Analysis Equipment HPLC, UPLC, GC, GCMS, LC/MS etc.
Chromatography is the broad term for laboratory techniques designed for the separation or analysis of complex mixtures. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. Different rates of migration cause the various constituents of the mixture to travel at different speeds, causing them to separate. Chromatography is used in many research and clinical labs in applications such as isolating new compounds and analyzing differences between compounds.
  • Compound Structures Analysis Equipment FT-IR, UV-VIS Spectrophotometer, XRD, NMR, NIR etc.
The molecular structure is analyzed by using visible and ultraviolet scattered
light. This instrument is used for measuring the scattered light obtained from a sample irradiated by laser light in the visible and ultraviolet range. When the laser light is scattered, a shift of wavelength (Raman shift) occurs. Based on the amount of shift, data on the vibrations and bonding conditions of the molecules constituting the sample can be obtained. The instrument is used not only for checking the composition and reactivity of our products, but also analyzing foreign matter mixed into the products or our clients’ compounds.
  • Elemental Analysis Equipment ICP, ICP-MS, IC, TN Analyzer, NC Analyzer, XRF etc.
Elemental analysis identifies and quantifies elements and molecular species in a sample, with detection ranges for trace and ultra-trace analysis spanning ppm to ppt levels, as well as bulk analysis. The range of techniques is far-reaching, including atomic absorption, arc spark, ICP-MS, ICP-OES, ESI-MS, XRF, and analyzers for carbon, sulfur, and nitrogen.
  • Surface Analysis Equipment Microscope, Spectrometer, TDS etc.
Surface analysis expertise from our experience and competent resources is available in the middle-east, specifically, Saudi Arabia and Bahrain. Client samples are easily transported to the appropriate RICI laboratory for surface analysis projects. Applications include research and development support, failure mode and effective analysis, troubleshooting, and quality control for our customers.
  • Thermal Analysis Equipment TG, DTA, DSC etc.
Thermal Analysis is important to a wide variety of industries, including polymers,
composites, pharmaceuticals, foods, petroleum, inorganic and organic chemicals, and many others. These instruments typically measure heat flow, weight loss, dimension change, or mechanical properties as a function of temperature. Properties characterized include melting, crystallization, glass transitions, cross-linking, oxidation, decomposition, volatilization, coefficient of thermal expansion, and modulus. These experiments allow the user to examine end-use performance, composition, processing, stability, and molecular structure and mobility.
  • Laboratory Equipment Flash Point Testers, Calorimeters, TOC Analyzers
A flash point tester is an instrument that determines the flash point of a sample, which is the temperature point at which the sample vaporizes to another composition state in the air that can be ignited. At that moment, the flash point apparatus can determine and measure the vapor pressure change in which this occurs, also known as the lowest limit of flammability. Therefore, vapor concentration can be determined by temperature. There are two main types of flash point analyzers: open cup flash point testers and closed cup flashpoint testers. The open type is intended to simulate an open and natural environment, whereas a closed type is more commonly used in laboratory testing.
  • Dew Point Analyzers, PH Meters, Conductivity Meters, Viscometers, Pour Point Testers etc.
