WebGuard columns are widely used in GC and GC/MS applications to protect the analytical column from contamination. When the guard column is a short piece of uncoated, deactivated fused silica tubing, the use of a guard column is also an inexpensive technique to extend the lifetime of capillary columns. WebCyfluthrin is moderately toxic to mammals with an oral LD50 of 850–1200 mg kg −1 in rats. Large doses of cyfluthrin cause excess salivation, irritability, tremors, incoordination, convulsions, and a fall in blood pressure. The acute toxicity of cyfluthrin increases at lower temperatures, and it is also acutely toxic when inhaled. Human
