What analytes can one distill with the MICRO DIST?
Cyanide, phenolics, sulfides, tritiated water, and ammonia. Practically any volatile analyte can be distilled. View our MICRO DIST Datapack for more details on these analytes.

Why would I want to use the MICRO DIST instead of the macro distillation method?
It's flexible, easy to set up, requires a modest equipment investment, saves time, reagents, and gives precision of 0.20% RSD. It also has a small footprint compared to the macro method and does not require the use of a fume hood.

Does Lachat have any real world sample data?
Data from real world samples, such as surface waters, well water, refinery samples and standard NIST soil samples are included in the data pack. We also have total cyanide spiked into WWTP sludge data.

How long does a distillation take?
The setup takes only a few minutes. The distillations themselves vary from 30 minutes for cyanide, ammonia, sulfide and tritium to 90 minutes for phenol.

Do I need a fume hood for the MICRO DIST?
No, as a matter of fact, MICRO DIST blocks should not be installed in a hood.

How much bench space does the MICRO DIST need?
About two feet (0.6 meters) in length, three feet (0.91 meters) in height and one foot (0.31 meters) in depth is the required working space.

Top
Can I reuse the tubes?
No, the membrane inside the tubes becomes fatigued after one steam distillation and cannot reliably be used afterwards.

How does one use the MICRO DIST tube?
It's easy: ask for a copy of our Users' Manual which has pictures and descriptions of the procedure.

What is the difference between user-fill and pre-filled? What are the advantages of each tube? What are the disadvantages of each tube?
The pre-filled tubes offer extra convenience as they already have the trapping solution in them. The trapping solution will remain stable in the pre-filled tubes for over one year if the aluminum bag remains heat sealed. Once the tube package is opened, it must be carefully re-sealed or the pre-filled tubes will dry out. The user-fill tubes can be made up in small quantities as needed, have an indefinite shelf life, and reduce shipping costs.

How long is the solution in the tubes stable after they have been distilled?
If the MicroDIST tubes are sealed with Parafilm, the solutions are stable for the recommended holding times.

Can I determine concentrations of the distallates/digestates using both manual methods and automated methods?
Yes, you can use an automated analyzer or manual method to measure the concentration of the analytes in MICRO DIST tubes.
