If you just want to know the isomer, Swim uses two Polarized lenses to view the pseudo-HCL salt disolved in  just enough ethanol.

>(You do want the dextro, not the levo, for the d-meth, right?)

no, the l-pseudo yeilds d-meth.

Apart from TFSE there is also www.rhodium.ws
I guarantee you my friend you'll be able to find all your answers in these two.

"The diastereoisomers, (-)-ephedrine and (+)-pseudoephedrine, are reduced to (+)-methamphetamine, whereas the enantiomers reduce to (-)-methamphetamine. The (±) mixture of either ephedrine reduces to racemic methamphetamine. The enantiomer and diastereoisomer of ephedrine selected as the precursor dictates what isomer of methamphetamine will be produced."
