Proficiency Test Program (PTP) is a very important work in the management of environmental analysis laboratory for National Institute of Environment Analysis (NIEA) in ROC. This program has been last for 10 years under the financial support of EPA, the main purpose of this program is working on the preparation and R/D of PE samples for EPA, which are used as Proficiency test sample for the management of environmental analysis laboratory in Taiwan. The major works of this year project include: 1.Study the preparation technique of PE samples in water with Chloride, Fluoride, Sulfate, Conductivity and Hardness in one bottle, hardness is a new item in this year#s project. 2.Study the technique for the preparation of TCLP PE samples with 8 heavy metals from real waste matrix. 3.Preparation of PE samples for water category in the PTP tests, including Ammonia Nitrogen, Nitrate, Nitrite, total phosphorous, Phenol groups, Boron, Silver, ABS, hexa-valent Chromium, Color, Cyanide, and Sulfide in water. At least, 41 batches, and 1730 bottles of PE samples had been prepared. 4.Preparation of PE samples of TCLP for Waste category in the PTP tests, including hexa-valent Chromium, Cadmium, Copper, Zinc, Chromium, Lead, Arsenic, Selenium, and Mercury. Two batches and at least 60 bottles for each batch had been prepared. 5.Transfer the PE sample preparation techniques established in past 10 years, including introduction in class: basic reference material, ISO/IEC Guide 31~35, how to design preparation plan, and real practice in laboratory. In first stage 10 items of preparation techniques had been transfer, those items were Ammonia Nitrogen, Nitrate, Nitrite, total phosphorous, Phenol Groups, Boron, Silver, ABS, hexa-valent Chromium and Color.
