simpler

Ostro's sample preparation plate uses a single solvent sample preparation method, allowing you to easily remove proteins and phospholipids from the sample matrix and improve the recovery rate of sample purification. This technology has been validated to be applicable to various acidic, alkaline, and neutral compounds, providing excellent results with higher reproducibility and helping to establish stable analytical methods. Unlike the protein precipitation (PPT) method, Ostro's sample preparation plate can remove phospholipids from the sample, avoiding their deposition on the analytical column or contaminating the ion source of the mass spectrometer. In addition, compared with liquid-liquid extraction (LLE) or solid-liquid extraction (SSLE), Ostro can also achieve the recovery rate of multi analyte mixtures with less sample preparation time.

Faster

Due to the lack of method development, Ostro simplifies the sample processing process and optimizes the sample processing flux through the use of sample preparation plates, significantly reducing sample preparation time. It can also be easily automated, providing you with results more quickly. Ostro collection solution can be directly injected without the need for drying and reconstitution steps, which can further save time. Compared with PPT, Ostro sample preparation plate can effectively remove signal interferents such as phospholipids. Its advantage is particularly helpful for analyzing large amounts of samples in a short period of time using fast and steep gradients. The Ostro sample preparation plate can remove phospholipids, avoiding their deposition after multiple injections, thereby increasing the normal operation time of the system and improving overall work efficiency.

Cleaner

Phospholipids are the main source of matrix effects, which can cause differences in analytical results, reduce sensitivity, and lead to unpredictable mass spectrometry results. Unfortunately, many commonly used sample preparation techniques such as PPT and LLE cannot effectively remove phospholipids. The Ostro sample preparation plate provides the best solution to this problem. Compared with other competitive technologies, Ostro can remove phospholipids more effectively, thereby avoiding differences in analysis results. Even when used to process multiple batches of human plasma samples, the results can still be maintained. Therefore, the Ostro sample preparation plate can provide you with excellent and comprehensive results.
