We do a MPI with kerosene based carrier. We want to switch over to a non-inflammable carrier for eg. water. Do any body guide on this?

RE: Magnetic Particle Inspection
I suggest you investigate the www.magnaflux.com website. They have a great deal of product information. As israelkk and ndeguy mentioned there is definitely a trade-off going to a water based solution. In addition to anti-corrosion agents water based solutions also need a wetting agent and an anti-foaming agent. Luckily, you can buy the particles already containing all the necessary additives from most suppliers (like Magnaflux). The biggest caution I will give about water based solutions is that you must constantly monitor them. It doesn't take much of an imbalance to really throw things off. If properly maintained, water based solutions work quite well.
