EPI-MTG New Facility

Cleared Site of EPI-MTG's New Facility

EPI-MTG is proud to announce the ground breaking on our new lab, office, and conference space located 1 mile east of I-45 on Rayford Road.  We will have close to 17,000 square feet of lab and office space in our new building.  This will allow us to work in a more fluid and efficient manner as well as expand our services/capabilities.  As well as a larger shop area and dedicated microscopy and analytical testing labs, we will have a dedicated area to host the inspection of evidence or material with easy access to our shop and analytical equipment.  

Energy Dispersive X-ray Spectroscopy (EDX)

EDX is an analytical technique used for the elemental analysis of a material. In EDX a beam of electrons bombards the top surface of the sample. If the incoming electron beam is of sufficient energy it will cause inner shell electrons of the affected atoms to become excited and thus ejected from its bond to the nucleus of the atom. When this happens, an electron from an outer, higher energy, shell drops down to take its place. That electron must release some of its energy in order to fit into the inner, lower energy shell. That release of energy, in X-ray form, is then collected, counted, and converted into weight or atomic percentages. EPI Materials Testing Group uses our EDX in the elemental analysis of many different materials in the daily process of running failure analyses and the wide array of testing services that we perform from corrosion products to identifying particles in filtrate.

HARDNESS TESTING

Hardness is the measurement of how resistant a material is to a permanent change in shape.  The hardness of a material is dependent on many different physical properties like ductility, strength, and toughness.  EPI-MTG has experience performing hardness testing on a wide range of alloys, as well as plastic, rubber, and ceramic/carbide.  EPI-MTG has the ability to perform hardness testing using the Knoop (HK), Vickers (HV), Rockwell (HRA, HRB, HRC, HRD, and HRE), and Brinell (BHN) hardness scales.
