X-Ray Detection Systems

Thermo Scientific NextGuard

The Thermo Scientific™ NextGuard™ X-ray system is designed to make moving from metal detection to X-ray detection easy, fast and inexpensive. It is ideal for finding dense or sharp objects in a wide variety of products as well as detecting errors like over/under fill or missing, misplaced, cracked or incorrectly formed products. The system enables compliance with worldwide HACCP and retailer food safety requirements.


Most X-ray detection systems project the X-ray beam from the top down in a narrow beam to a linear detector. This makes using the X-ray image for product inspections easier, but also means taller products must get narrower to always fit in the beam. With NextGuard we wanted to make it simple for users, so we project a wide X-ray beam from the bottom up to a non-linear detector that assures everything is completely inspected. Any differences in X-ray signal across the arch-shaped detector are automatically calibrated out when you set-up your product.


Product Inspection

    X-Ray Detection


    Product verification software option allows users to execute a wide range of size, position and count inspections.

    Additional algorithms target the detection of less dense contaminants such as glass or rocks in complex, textured products such as nuts or tea bag boxes.

    Optional mass estimation software uses the density information in the X-ray image to estimate weight and detect under/over filled products.

    Configurable for dual rejection, separating contaminated products from other quality errors.

    Standard system processor is now six times faster than the first generation NextGuard system, supporting high-speed contaminant detection and inspection as well as improved user responsiveness.


    0.4mm-pixel detector offers 3.2 times better resolution for improved metal detection in lightweight, homogeneous products such as powders or cheese.
