A syringe feeds the sample through the measuring cell. Individual particles reduce the intensity of a light beam; the signals determine particle counts and size classes. A PC handles control and analysis.<\/p>\n<h2>Sensor and software selection<\/h2>\n<p>Two sensor and software combinations are available for pharmaceutical testing and general liquid analysis.<\/p>\n<div class=\"pm-table-wrap\">\n<table class=\"pm200-configurations\">\n<thead>\n<tr>\n<th scope=\"col\">Feature<\/th>\n<th scope=\"col\">Pharmaceutical testing<\/th>\n<th scope=\"col\">General liquid analysis<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td data-label=\"Feature\">Software<\/td>\n<td data-label=\"Pharma\">Pharmaceutical analysis<\/td>\n<td data-label=\"General analysis\">General liquid analysis<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Feature\">Particle size range with latex calibration<\/td>\n<td data-label=\"Pharma\">1\u201350 \u00b5m, linear<\/td>\n<td data-label=\"General analysis\">0.9\u2013139 \u00b5m<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Feature\">Maximum particle concentration<\/td>\n<td data-label=\"Pharma\">100,000 particles\/mL<\/td>\n<td data-label=\"General analysis\">120,000 particles\/mL<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Feature\">Particle size channels<\/td>\n<td data-label=\"Pharma\">Up to 8 fixed channels<\/td>\n<td data-label=\"General analysis\">Up to 256 freely selectable channels<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Feature\">Sensor flow rate<\/td>\n<td data-label=\"Pharma\">20 mL\/min<\/td>\n<td data-label=\"General analysis\">30 mL\/min<\/td>\n<\/tr>\n<tr>\n<td data-label=\"Feature\">Measuring cell dimensions<\/td>\n<td data-label=\"Pharma\">230 \u00d7 250 \u00b5m<\/td>\n<td data-label=\"General analysis\">300 \u00d7 300 \u00b5m<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>The ranges apply with latex calibration.

Residual contamination testing and further particle size analysis can be performed with suitable sample delivery and an application-specific configuration.<\/p>\n<p>Colour, turbidity, high viscosity and gas bubbles can affect light obscuration measurement. Sample preparation, sample delivery and chemical compatibility must suit the sample.<\/p>\n<h2>Analysis and documentation<\/h2>\n<h3>Analysis for pharmaceutical testing<\/h3>\n<p>The pharmaceutical analysis software supports measurement and analysis according to USP requirements and company-specific methods. Measurement series and diluted samples can be evaluated, with results available as tables or reports. The applicable test method and required documentation functions inform the choice of configuration.<\/p>\n<h3>Analysis for general liquid applications<\/h3>\n<p>The general liquid analysis software reports results cumulatively or by size class, based on particle count, volume or mass. Data can be exported for further processing in Microsoft Excel.<\/p>\n<h2>Configuration and scope of supply<\/h2>\n<p>The measurement system combines syringe-based sample delivery, a sensor, analysis electronics, software and a PC.
