Chemical and Analytical Laboratories: The work of chemical and analytical laboratories is directed to all areas concerning the production of pulp, paper and board. 3.1 Evaluation of the Quality of Pulp, Paper, Board and Products Made from Them We are providing chemical tests in the meaning of standards STN, CSN, DIN, ISO, EN or other standards. The main set of analysis is the following: Limiting viscosity number Organic bounded halogens OX Overall halogens TX Kappa number Lignin Alpha cellulose Pentosans Unhealthy resins Starch Surface pH Fiber length analysis Formaldehyde Glyoxal Melamins Borates Sulfates Fluorides Nitrates Nitrites Metal and non metal elements Heavy metals Final results of the analyses are basis for proving certificates, evaluation of products by side of their corrosion properties, assessment of paper package materials that are in contact with foot in the meaning of Foot Codex of Slovak Republic, etc. 3.2 Solution of Problems in the Technology of Pulp, Paper and Board Producing Processes In the area of pulp production, we provide completed analysis of different wood sorts, input chemicals, we are evaluating the quality of pulp in final technological stage, we analyze pulping and bleach liquors, spent liquors, condensates, bleaching liquors, we investigate the composition of scale in the equipment. In the area of paper and board production we evaluate chemical processes during additives application, such as starch, sizes, etc. 3.3 Monitoring of Waste Waters, and Waste Sludge Analysis Analyzing waste water and sludge we keep the standard �methods of analytic control of waste�, which was published by Slovak Agency for Life Environment. We are monitoring the waste water from the point of view of important water indicators (such as NL, COD, BOD5, TOC, IC, TC, TX, AOX, EOX, POX, heavy metals, color, phenols and surfactants). 3.4 Balance of Sewage Units, Cleaning of Waste Waters We work out the final result of waste water monitoring and we work out balances of sewage units of any organization, where each flow of waste water is characterized by side of stock flow and by demanded indicators of pollution. To make a balance we need to know the overall flow of waste waters, their composition, composition of both partial and mixed streams and program for computer analysis of material balance of the sewage system. This method is specially appropriate in systems where are not suitable conditions for device stock flows measuring of each flow of the stream system. This method was successfully applied in many pulp and paper mills of Slovak Republic and Czech Republic. In the area of waste water treatment we test clarification by chemical and biological process.

Comparative Measurement Between Laboratories: Correct measurements of selected instruments of Institute is being tested by cyclic comparative measures that are compared with foreign laboratories, such as STFI and STORA (Sweden), PIRA (England) and PTS (Germany). On the base of these results, VUPC laboratories make cyclic comparative measures for Slovak laboratories that use this service while obtaining the certificate of quality ISO 9000. After taking these tasks CEPI - CTS (CEPI Comparative Testing Service) our laboratories are about to provide this service for countries of V4 (Slovak Republic, Czech Republic, Poland and Hungary). Physical and mechanical characteristic measurements bidden to foreign laboratories are these ones: basic weight (it can be used for control of air-condition) thickness determination of water absorbtivness - Cobb method air permeability Bendtsen method Bekk method Gurleya method smoothness Bekk method Bendtsen method roughness by Perker IGT surface resistance of paper tearing resistance - Elmendorf method burst strength - Mullen method (for paper and board) CMT CCT RCT ECT FCT puncture resistance bending stiffness brightness We also offer direct verification of devices using physical method, as follows: printing device IGT AIC-2, AIC-5, eventually Grafotechna TJ-3 puncture resistance device setting up of �Elrepho� devices for the secondary reference standard of ISO IR 3 with or without the content of fluorescence brightening substances LC setting up of TECHNIBRITE devices for the secondary reference standard of ISO IR 3 re-calibration of working standards or re-calibration of ceramic plates based on reference paper standard of ISO IR 3 Brightness measuring devices that are calibrated by mentioned methods are connected to the international authorized office ISO ( in accordance with ISO 2469 standard). We offer linking of your equipment to VUPC Central Laboratories devices on the base of comparative measuring. This way you can control the correct measuring of your equipment.
