Niton handheld analysers go higher

Cladding on buildings is in the spotlight. To prevent another Grenfell it is more critical than ever to know the materials on existing structures and to check the materials to be used on new structures.
Investigating materials in tight spots on tall buildings over 50 m above street level is now much easier with a handheld Niton analyser, but you need a good head for heights. Barry Hunt from IBIS Chartered Surveyors uses a portable X-ray fluorescence analyser to check the metals used in cladding on buildings up to 14 storeys high. Such surveys are proving invaluable in diagnosing many different types of condition. In expert hands an instant elemental analysis can mitigate costly, time-consuming laboratory sampling and analysis.
The following are just some of the many potential applications that have already been carried out using the equipment:
- Identification of stone type and elemental make-up.
- Establishing the lead content of paint and contamination of background materials.
- Distinguishing different grades of steel and other metals.
- Determining the thickness of protective coatings to metals.
- Assist in determining the presence of salts affecting different masonry materials.
- Assessing the cement binder type in mortar and concrete.
- Measuring the content of precious metals.
- Revealing the nature of surface encrustations to masonry.
The XRF instrument has already proved especially successful in recognising the presence of lead-based paint, where hundreds of measurements may be taken in a single day from numerous locations. This has avoided additional works when stripping paint and has saved on the subsequent waste disposal.
The analyser can also run instant checks on critical items such as stone cladding fixings by determining the grade of stainless steel present. Metals and alloys are identified precisely by comparing each against certified reference standards. With the recent spotlight on external cladding, now more than ever, it is essential to check that materials supplied are of the right quality. A few hours on site undertaking such analysis provides reassurance.
The X-ray fluorescence analyser is one of the many different items of equipment IBIS employs, making their facade surveys considerably more accurate than the hands-off methods offered by drones, lasers and other remote techniques. IBIS uses experts who abseil, and can offer detailed advice on protection, cleaning, maintenance, planned works and facade retention issues.
