There are 2 options to work around this problem.
1. Since all the data is
rever
sed it can be reversed back so that it will then be correct.
2. Another way to correct the impactor data is use the dry nephelometer pressure. The dry nephelometer varies between 2 pressures. The nephelometer pressure is higher when the impactor is 10um and lower when it is 1um.
