Even minor oversights, such as using an unsuitable container or failing to secure the sample properly, can lead to distorted results and incorrect operational decisions. <\/p>\n<p class=\"post__paragraph\">This is why it is so important to use proven procedures and appropriate materials for the collection and transport of oil and lubricant samples. Standardising these processes not only increases the reliability of analyses, but also allows the full potential of oil diagnostics to be harnessed in maintenance. In practice, this means greater machine operational safety, cost optimisation and better planning of maintenance activities. <\/p>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t      <\/div>\n                \n          \n        \n      <\/article>\n    <\/div>\n  <\/div>\n<\/section>\n\n\n<section class=\"contact-persons alignwide\">\n  <div class=\"container\">\n    <div class=\"row\">\n\n      <div class=\"offset-lg-2 offset-md-0 col-lg-8\">\n\n        \n          <h2 class=\"heading heading--line\">contact<\/h2>\n\n        \n        \n          <h3 class=\"heading heading--large\">Do you have any questions about our diagnostic services?<\/h3>\n\n        \n        \n          <p class=\"desc\">Please contact us directly:<\/p>\n\n        \n      <\/div>\n\n      \n        <ul class=\"offset-lg-2 offset-md-0 col-lg-9 listing\">\n\n          \n            \n            <li class=\"listing__item\">\n\n\t            \n\t\t\t\t\t\t\t\t<div class=\"listing__inner-wrapper\">\n\t\t\t\t\t\t\t\t\t<div class=\"listing__image-wrapper\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" src=\"https:\/\/ecol.eu\/wp-content\/uploads\/2024\/06\/katarzyna-paryz-400x400-2.jpg\" class=\"listing__image\" alt=\"\" loading=\"lazy\">\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<div class=\"listing__inner-details\">\n\n\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t<h3 class=\"listing__heading heading heading--b\">Katarzyna Pary\u017c<\/h3>\n\n\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t<p class=\"listing__position\">Head of sales office<\/p>\n\n\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t<a href=\"tel:+48666047697\" class=\"listing__link\" target=\"\"><svg width=\"14\" height=\"14\" viewBox=\"0 0 14 14\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n  <path d=\"M13.1403 9.8875C13.1044 9.85906 10.5 7.98175 9.78512 8.1165C9.44387 8.17688 9.24875 8.40963 8.85719 8.87556C8.79419 8.95081 8.64281 9.13106 8.52513 9.25925C8.27767 9.17854 8.03629 9.08029 7.80281 8.96525C6.59773 8.37857 5.62406 7.4049 5.03737 6.19981C4.92225 5.96637 4.824 5.72498 4.74337 5.4775C4.872 5.35938 5.05225 5.208 5.12925 5.14325C5.593 4.75387 5.82619 4.55875 5.88656 4.21662C6.01038 3.50787 4.13437 0.8855 4.11469 0.861875C4.02957 0.740281 3.91849 0.639127 3.78948 0.565733C3.66047 0.492338 3.51676 0.448537 3.36875 0.4375C2.60837 0.4375 0.4375 3.25369 0.4375 3.72794C0.4375 3.7555 0.477313 6.55725 3.93225 10.0717C7.44319 13.5227 10.2445 13.5625 10.2721 13.5625C10.7467 13.5625 13.5625 11.3916 13.5625 10.6312C13.5516 10.4838 13.508 10.3405 13.435 10.2119C13.362 10.0833 13.2614 9.97248 13.1403 9.8875Z\" fill=\"black\"\/>\n<\/svg>\n666 047 697<\/a>\n\n\t\t\t\t\t\t\t\t\t\t\n                    \n\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t<a href=\"mailto:k.paryz@ecol.eu\" class=\"listing__link\" target=\"\"><svg width=\"14\" height=\"14\" viewBox=\"0 0 14 14\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n  <g clip-path=\"url(#clip0_447_7182)\">\n    <path d=\"M8.17001 8.57754C7.82171 8.80974 7.41713 8.93249 7 8.93249C6.5829 8.93249 6.17832 8.80974 5.83002 8.57754L0.0932148 4.75289C0.0613867 4.73167 0.0303789 4.70955 0 4.6868V10.9539C0 11.6724 0.583105 12.2427 1.28879 12.2427H12.7112C13.4297 12.2427 14 11.6596 14 10.9539V4.68677C13.9695 4.70957 13.9385 4.73175 13.9066 4.75299L8.17001 8.57754Z\" fill=\"black\"\/>\n    <path d=\"M0.548242 4.07039L6.28504 7.89507C6.50221 8.03985 6.75109 8.11223 6.99997 8.11223C7.24888 8.11223 7.49779 8.03982 7.71496 7.89507L13.4518 4.07039C13.7951 3.84166 14 3.45884 14 3.04568C14 2.33526 13.422 1.75732 12.7116 1.75732H1.28836C0.577965 1.75735 0 2.33529 0 3.04636C0 3.45884 0.204969 3.84166 0.548242 4.07039Z\" fill=\"black\"\/>\n  <\/g>\n  <defs>\n    <clipPath id=\"clip0_447_7182\">\n      <rect width=\"14\" height=\"14\" fill=\"white\"\/>\n    <\/clipPath>\n  <\/defs>\n<\/svg>\nk.paryz@ecol.eu<\/a>\n\n\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\n\t\t\t\t\t\t\t\n            <\/li>\n\n          \n        <\/ul>\n\n      \n    <\/div>\n  <\/div>\n<\/section>\n\n\n<section class=\"news alignwide\">\n  <div class=\"container\">\n    <div class=\"row justify-content-center\">\n      <div class=\"offset-lg-2 col-lg-10\">\n\n        \n          <h2 class=\"heading heading--line\">see also<\/h2>\n\n        \n      <\/div>\n\n      \n        <ul class=\"col-lg-10 news-list\">\n\n          \n            \n            <li class=\"news-list__item\">\n              <a href=\"https:\/\/ecol.eu\/en\/knowledge-base\/jak-pobrac-probke-do-analizy-instrukcja\" class=\"news-list__inner news-list__inner--wide\">\n                <div class=\"news-list__image-wrapper\">\n                  <img decoding=\"async\" src=\"https:\/\/ecol.eu\/wp-content\/uploads\/2024\/06\/ecol-pojemniki.png\" class=\"news-list__image\" alt=\"Fot.
