![]() ![]() The Spectra S1 and S2 breast pumps feature what Spectra calls Natural Nursing Technology. When it comes to choosing between the S1 and S2, the biggest difference is that the S1 comes with a rechargeable battery. The Spectra S1 and Spectra S2 are mom favorites because they are quiet, comfortable, and efficient! When I was pregnant with my second, I asked around and found that many moms felt that they had better results when they used a Spectra. With my first baby, I used a Medela pump, and struggled with a low milk output when pumping.

Check out this post for some suggestions for pumping with your Spectra breast pump and a suggested method that many moms consider to be the best settings for Spectra S1 or S2 breast pump. It can be a bit overwhelming to begin with, as finding the right settings for you can take a bit of work. With multiple modes and settings, the Spectra pumps allow for each mom to customize her pumping sessions to meet her personal needs at the moment. The Spectra S1 and S2 breast pumps favorite choices among moms. If you are going to be spending time away from your baby, then pumping breast milk is an important aspect to learn about.

In addition, the proposed method can maintain the efficiency and cost of LIBS measurement.Ĭlassification Coal Discrimination Laser-induced breakdown spectroscopy Measurement Multiple settings.Ĭopyright © 2021 Elsevier B.V. The results show that the use of multiple-settings spectra can significantly improve the sample discrimination accuracy from 81.8% to 96.4%. Specifically, the sample spectra were collected with different laser energy and delay time, and processed by principal component analysis (PCA) and Davies-Bouldin index (DBI). The effectiveness of the proposed method is theoretically verified and then tested on 11 similar coal samples. For each sample, it adopts different sets of experimental parameters and obtains a group of spectra to increase the fingerprint spectral information. In this work, we propose a new method to increase the spectral difference between similar samples, namely multiple-setting spectra. This can lower the sensitivity of LIBS measurement and pose a threat to the accuracy and robustness of LIBS qualitative analysis. ![]() When samples have the same main components and similar component concentrations, the difference in their spectral intensities becomes less obvious. In traditional LIBS measurement, sample spectra are generally collected based on a single set of fixed experimental parameters, such as laser energy and delay time. ![]() Laser-induced breakdown spectroscopy (LIBS) is a promising multi-elemental analysis technique and has the advantages of rapidness and minimal sample preparation. 8 Beijing Research Institute of Chemical Engineering and Metallurgy, CNNC, Beijing 101149, China.7 Jinneng Holding Shanxi Electric Power Tashan Power Generation Co., Ltd., Shanxi 037038, China. ![]()
