you can use on R22 also yes, it works on all refrigerants.

What will happen if used on a 1-ton system?

You will probably be putting too much in. They make a smaller dosage unit, but it doesn't have the dye in it. You can get a dye injector and inject the dye separately. You can use the smaller unit on automotive applications. The company is in St. Louis, MO and I had called their tool free number. Very Helpful.

Can I use this sealer in an empty mini split using pressurized nitrogen?

Needs to be installed when charging the system as it needs to circulate for about an hour with system running after fully charged
