Halogen Testing

Additional Halogen Testing Information

Halogen Interferences & Samples Size

Midwest Microlab is capable of testing solid or liquid samples for the total percentage of Halogens with a range of 0.04% (4,000 ppm) to 100%. Accuracy for Halogen testing is +/- 0.4. Please refer below for known Halogen interferences and Sample Size according to Customer Theory. Each element Halogen Analysis & Techniques can be found with its individual elements page.

Interferences Associated with Halogen Testing:

Bromine interferences include : Al, Cl, Eu, Hg, I, Mg, Na, Ni, Se, Si, Sn and Ti. 

Chlorine interferences include:  Al, Br, Eu, Hg, I, Mg, Na, Ni, Se,Si, Sn and Ti. 

Fluorine interferences include: Ba(OH)2 , Ca(OH)2 , KOH , LiOH , NaOH , Sr(OH)2 , Al, B, Ba, Ca, Fe, K, La, Li, Na, Si and Sr.

Iodine interferences include: Cl, Cu, and Se. 

Please note the interferences above cannot be circumvented during analysis. Irregular results can be reported due to an interference within the molecular formula of the sample. Please note irregular results due to interferences cannot be interpreted by the chemists. Midwest Microlab chemists will perform requested analysis and report results as found with the understanding that the submitter understood the interferences associated and how it may affect results. Please indicate all elements or the molecular formula on the submission form.  If Bromine and Chlorine are found within the same sample molecular formula, then neither Bromine nor Chlorine can be performed due to both testing using the same indicator.

Turnaround Time

Standard Turnaround time for the total percentage of Bromine and Chlorine results is within 4 business days. RUSH services are available for an additional fee per sample,per analysis with per single run. Rush results turnaround time for Bromine and Chlorine analysis is within 2-3 business days. 

Fluorine and Iodine testing are complex and labor intensive determination. Standard Turnaround time for the total percentage of Fluorine and Iodine results is within 5 business days. RUSH services are available for an additional fee per sample, per analysis with per single run. Rush results turnaround time for Fluorine and Iodine analysis is within 3-4 business days. 

Midwest Microlab does NOT handle any samples containing Osmium, Uranium, or Thallium within the molecular formula.Midwest Microlab is able to perform samples with Depleted Uranium but must be clearly indicated on the submission form.  Please indicate on the comments section of the submission form if samples have a high toxicity or strong stench. We do not handle any Finished Pharmaceuticals for release or highly volatile liquid samples with boiling points of less than 40 deg C.
