Antimon – Wikipedia

Egenskaper. Antimon är en utomordentligt spröd metall som i rent tillstånd lätt kristalliserar i stora romboedrar. Som halvmetall har antimon fyra allotroper . I kemiskt avseende liknar antimon metalloiderna inom kvävegruppen, men räknas normalt på grund av sina mekaniska egenskaper till metallerna.

What is Peak Tailing?

What is Peak Tailing? Aug 08 2014. An ideal chromatography peak is a nice sharp symmetrical shape, a Gaussian peak, on a flat baseline. A peak can deviate from this ideal in several different ways. It can become asymmetrical, flatten and become broader, or the baseline can rise. One of the common shifts away from a Gaussian peak is when the ...

LABTips: How to Prevent Tailing Peaks in HPLC

While column overloading is typically more associated with peak fronting or "shark fin" shaped peaks, both mass overload and volume overload could also cause peak tailing across the chromatogram. 7 To test for mass overloading, simply dilute your sample to see if the peak tailing lessens or resolves. For volume overload, try injecting less ...

Tailings from a tantalum mining operation were comparatively sandy, with only 38% fines. Table 1.

Tailing Loops And How To Cure Them

If a tailing loop is the disease, drift is the penicillin. A bit of drift – even a few inches- takes the edge off and efficiently lengthens the stroke. Experiment with wrist rotation, focus on making the turnover later and later. Maybe the best way to understand tailing loops is learning how to form them. Try this drill.
