A new four-way x-ray detector can offer manufacturers of baby food
and other high viscosity products a high probability of glass
contaminant detection in their packaging, according to its

Mettler-Toledo told that its Glasschek Quad x-ray product has been designed to improve detection of glass shards in jarred baby food products, though was also being developed for larger forms of glass packaging as well. As part of the x-ray's design, the scanner combines three horizontal x-ray beams with a single vertical scanner to overcome blind spots created by a pack's sidewalls, base and neck by offering better coverage of a product within the jar. The product, which can also be used to find foreign bodies in metal and stone, is not the first four-way x-ray system to be developed to test for contaminants in food products However, a company spokesperson claimed that while the low power Glasschek Quad is a higher cost alternative x-ray for manufacturers, it offers a high detection rate that can help to reduce outgoings related to product recalls and well as running costs. "The system is all self-contained including software and a low power x-ray that can be kept cool using standard air conditioning equipment,"​ he stated. "The product can ensure minimum false rejects that are also contributors to cost."​ The company claims that the x-ray can maintain this level of sensitivity even when the device is being used at a detection rate of 1,000 jars per minute. Mettler-Toledo says that the system is operated through a user-friendly interface, which, along with product menus, can allow plant workers to set up or adjust the scanner for a variety of products without requiring an engineer. Another feature of the Glasschek Quad is that it can be used to measure product fill-levels within a jar, while also complying with hygiene standards for cleaning and maintenance, according to the manufacturer. According to the group, the system is designed primarily for use in wide-mouth glass jars, though it was looking to work with processors to test the compatibility of the Glasschek on other product types.
