Twining Inc

Since its founding in 1986, Calscience Environmental Laboratories has sought to achieve a single goal: to meet or exceed the expectations of its customers. The company is a testing laboratory that services the environmental engineering community, and provides a variety of analytical services to industry and government. Calscience s facilities, instrumentation and staff have expanded to include a full-service environmental testing company that offers analysis of fuels and solvents, hazardous waste, groundwater, storm water, soil and marine sediment, soil vapors and ambient air. The company is located in Garden Grove, Calif., and serves clients throughout the United States and the world.

Since 1970, PhotoMetrics has been solving production and failure analysis problems through chemical analysis and materials characterization. We are a commercial analytical laboratory located in Southern California offering state-of-the-art equipment, facilities and instrumentation, including, Field-Emission SEM for high resolution work, and Microelectronics Failure Analysis - Complete service for construction and failure analysis of semiconductor devices. Obtain accurate line widths, diffusion depths and film thicknesses using precision cross-sectioning and Scanning Electron Microscope imaging. Micro-contaminant Analysis - Identification of organic and inorganic micro-particles, liquid and solid films. Surface analysis techniques - for thin film characterization. Analyze the top few molecular layers of your sample with depth profiles to 2000 nm. Identify stains, surface oxidation, metal diffusion, catalyst degradation and measure film thicknesses. Organic and Inorganic Chemical Analysis - Qualitative and quantitative elemental analysis of compounds as solids, liquids and gases. Polymers are identified from a few nanograms of material, elemental analyses require much less.
