SepraSol Liquid/Gas Coalescers - Pall Corporation
Many manufacturers of coalescers measure efficiency using the dioctyl phthalate (DOP) test. The DOP test was not originally designed to measure the performance of a coalescer under operating conditions seen in the oil and gas industry. Rather, the DOP test is performed under the following conditions:
Solutions for Dioctyl Phthalate (DOP) tested high efficiency
Dioctyl Phthalate, DOP'' as it is referred to in chemical abbreviation form, is added in small test quantities at the factory, at three Department of Energy (DOE) operated HEPA filter test facilities, and in the installed duct work at various operating laboratories or production facilities.
Comparison of Respirator Filter Penetration by Dioctyl
High-efficiency particulate respirator filters are tested against DOP in the United States and against NaCl in Great Britain. The DOP test is faster, but impractical for a degradable filter such as resin-impregnated wool batt. The feasibility of using a NaCl aerosol to test all types of particulate respirator filters is discussed.

HEPA efficiency is rated using a thermal dioctyl phthalate (DOP) test. The test dust for HEPA filters is mono-sized, 0.3 m diameter, DOP particles, generated by vaporization and c ondensation. Alternative aerosols can also be used as specified or required for given applications.
Laboratory filtration - Fisher Sci
for a stated airborne particle size. The dioctyl phthalate (DOP) test is commonly used, wherein the filter is tested with an aerosol containing 0.3 m particles. Particle retention (liquid) In a filtration process, the particle retention efficiency of a depth-type filter is often expressed in terms of
- What is dioctyl phthalate (DOP)?
- 1. Introduction Dioctyl phthalate (DOP) is one of the most widely used plasticizers with low volatility and high plasticizing efficiency. Although new product like dioctyl terephthalate is more recommended, DOP accounts for more than half of the market share for plasticizers.
- Can halogen-free deep eutectic solvent promote DOP synthesis in a biphasic system?
- In this work, the process intensification of reactive extraction strategy is proposed to promote DOP synthesis in a biphasic system, with the halogen-free deep eutectic solvent (DES) [Im:2PTSA] as dual solvent-catalyst.
- What is a DOP test?
- The DOP test is performed using an oily aerosol called dioctyl phthalate. This method has long been used in the nuclear and pharmaceutical industries because of its ability to accurately measure the removal efficiency of high-performance air filters.
- Is DOP plasticizer soluble in water?
- DOP Plasticizer, or Dioctyl Phthalate, is a clear, colorless, and oily liquid commonly used to enhance the flexibility of plastics. It has a high boiling point and is insoluble in water but soluble in organic solvents like ethanol and ether. What is Dop Plasticizer?
- Where can I buy phthalic anhydride and p-toluenesulfonic acid?
- Materials Dioctyl phthalate, phthalic anhydride, 2-ethylhexanol, n-tridecane, choline chloride, imidazole, and p -toluenesulfonic acid are purchased from Adamas-beta (Shanghai, China) with purity above 99%.
- How does a DOP detector work?
- How it works: During DOP detection, the instrument generates a certain concentration of DOP particles and uses a photometer to detect the difference in aerosol concentration before and after the filter.
